pinctrl: Drop TZ1090 drivers

Now that arch/metag/ has been removed, along with TZ1090 SoC support,
remove the TZ1090 pinctrl drivers. They are of no value without the
architecture and SoC platform code.

-ImgTec TZ1090 PDC pin controller
-
-Required properties:
-- compatible: "img,tz1090-pdc-pinctrl"
-- reg: Should contain the register physical address and length of the
-  SOC_GPIO_CONTROL registers in the PDC register region.
-
-Please refer to pinctrl-bindings.txt in this directory for details of the
-common pinctrl bindings used by client devices, including the meaning of the
-phrase "pin configuration node".
-
-TZ1090-PDC's pin configuration nodes act as a container for an arbitrary number
-of subnodes. Each of these subnodes represents some desired configuration for a
-pin, a group, or a list of pins or groups. This configuration can include the
-mux function to select on those pin(s)/group(s), and various pin configuration
-parameters, such as pull-up, drive strength, etc.
-
-The name of each subnode is not important; all subnodes should be enumerated
-and processed purely based on their content.
-
-Each subnode only affects those parameters that are explicitly listed. In
-other words, a subnode that lists a mux function but no pin configuration
-parameters implies no information about any pin configuration parameters.
-Similarly, a pin subnode that describes a pullup parameter implies no
-information about e.g. the mux function. For this reason, even seemingly boolean
-values are actually tristates in this binding: unspecified, off, or on.
-Unspecified is represented as an absent property, and off/on are represented as
-integer values 0 and 1.
-
-Required subnode-properties:
-- tz1090,pins : An array of strings. Each string contains the name of a pin or
-  group. Valid values for these names are listed below.
-
-Optional subnode-properties:
-- tz1090,function: A string containing the name of the function to mux to the
-  pin or group. Valid values for function names are listed below, including
-  which pingroups can be muxed to them.
-- supported generic pinconfig properties (for further details see
-  Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt):
-  - bias-disable
-  - bias-high-impedance
-  - bias-bus-hold
-  - bias-pull-up
-  - bias-pull-down
-  - input-schmitt-enable
-  - input-schmitt-disable
-  - drive-strength: Integer, control drive strength of pins in mA.
-      2: 2mA
-      4: 4mA
-      8: 8mA
-      12: 12mA
-  - low-power-enable: Flag, power-on-start weak pull-down for invalid power.
-  - low-power-disable: Flag, power-on-start weak pull-down disabled.
-
-Note that many of these properties are only valid for certain specific pins
-or groups. See the TZ1090 TRM for complete details regarding which groups
-support which functionality. The Linux pinctrl driver may also be a useful
-reference.
-
-Valid values for pin and group names are:
-
-  pins:
-
-    These all support bias-high-impediance, bias-pull-up, bias-pull-down, and
-    bias-bus-hold (which can also be provided to any of the groups below to set
-    it for all gpio pins in that group).
-
-    gpio0, gpio1, sys_wake0, sys_wake1, sys_wake2, ir_data, ext_power.
-
-  mux groups:
-
-    These all support function.
-
-    gpio0
-        pins:       gpio0.
-        function:   ir_mod_stable_out.
-    gpio1
-        pins:       gpio1.
-        function:   ir_mod_power_out.
-
-  drive groups:
-
-    These support input-schmitt-enable, input-schmitt-disable,
-    drive-strength, low-power-enable, and low-power-disable.

-        pins:   gpio0, gpio1, sys_wake0, sys_wake1, sys_wake2, ir_data,

-Valid values for pin and group names are:

-    These all support bias-high-impediance, bias-pull-up, bias-pull-down, and
-    bias-bus-hold (which can also be provided to any of the groups below to set
-    it for all pins in that group).
-
-    They also all support the some form of muxing. Any pins which are contained
-    in one of the mux groups (see below) can be muxed only to the functions
-    supported by the mux group. All other pins can be muxed to the "perip"
-    function which enables them with their intended peripheral.
-
-    Different pins in the same mux group cannot be muxed to different functions,
-    however it is possible to mux only a subset of the pins in a mux group to a
-    particular function and leave the remaining pins unmuxed. This is useful if
-    the board connects certain pins in a group to other devices to be controlled
-    by GPIO, and you don't want the usual peripheral to have any control of the
-    pin.
