xdma_event_intr1.clkout2 pad can be used to source clock
from either 32K OSC or any of the PLL (except MPU) outputs.
On the existing AM335x based boards (EVM, EVM-SK and Bone),
this pad is used to feed the clock to audio codes.

So, this patch configures the pinmux to get clkout2 on the pad.

With DT support, where naming convention is based on base-addr

This patch changes UART numbering as per TRM, as uart0-5.

Add pinmux configurations for gpio based user-keys to am335x-bone.
In this patch, only single named mode/state is added and these pins
are configured during pinctrl driver initialization.

Default mode is nothing but the values required for the module during
active state. With this configurations module is functional as
expected.

Ideally in common SoC dtsi file should set all modules
to "disabled" state and it should get enabled in respective
EVM/Board dts file as per usage.

This patch sets default status of all modules to "disabled"
state in am33xx.dtsi file. Currently there are no modules
supported as part of Bone and EVM dts support, so care
to add entry "status = "okay"" while adding support for any
module.
