When IRQ handling was moved to rmi_driver in 3aeed5b5 the naming of the
interrupt changed from "rmi4_i2c" to "2-0020" (or similar). This patch
restores the previous behaviour and makes the interrupt easier to identify
in /proc/interrupts.

ar1021_i2c also supports the ar1020 device I'm using. This is tested.
They also share the same datasheet:

So let users see that they have a compatible in front of them by adding
AR1020 to the driver's description.

We should not be forcing edge triggered interrupt, but rather let platform
decide the kind of trigger it needs to use. Also, the driver is not quite
safe with regard to edge-triggered interrupts as it does not try to kick
the controller after requesting/enabling IRQ.

The name field in structure i2c_device_id is 20 characters, and we expect
it to be NULL-terminated, however we are trying to stuff it with 21 bytes
and thus NULL-terminator is lost. This causes issues when one creates
device with name "MICROCHIP_AR1021_I2C" as i2c core cuts off the last "C",
and automatic module loading by alias does not work as result.

The -I2C suffix in the device name is superfluous, we know what bus we are
dealing with, so let's drop it. Also, no other driver uses capitals, and
the manufacturer name is normally not included, except in very rare cases
of incompatible name collisions.

There are several quirky Xbox One pads that depend on initialization
packets that the Microsoft pads don't require. To deal with these,
I've added a mechanism for issuing device-specific initialization
packets using a VID/PID-based quirks list.

For the initial set of init quirks, I have added quirk handling from
Valve's Steam Link xpad driver[0] and the 360Controller project[1] for
macOS to enable some new pads to work properly.

This should enable full functionality on the following quirky pads:
0x0e6f:0x0165 - Titanfall 2 gamepad (previously fully non-functional)
0x0f0d:0x0067 - Hori Horipad (analog sticks previously non-functional)
0x24c6:0x541a - PowerA Xbox One pad (previously fully non-functional)
0x24c6:0x542a - PowerA Xbox One pad (previously fully non-functional)
0x24c6:0x543a - PowerA Xbox One pad (previously fully non-functional)

When submitting the support for the ACPI0011 windows tablet keys device I
mapped the "windows" logo homekey to KEY_HOMEPAGE. But this is inconsistent
with how it is done on windows tablets using the old PNP0C40 ACPI device
and it does not match the HUT spec, which says that usage-page 7 usage 0xe3
is "Keyboard Left GUI".

This commit maps usage-page 7 usage 0xe3 to KEY_LEFTMETA fixing this.
