Add support for SW46-1 and SW46-2 as switches using the gpio-keys
framework.

v2:
- Don't adjust the pin-config bias
SW_LID and SW_DOCK are selected as low-impact switch events for the
default configuration. Would SW_RFKILL_ALL, and SW_MUTE_DEVICE be
preferred as more 'functional' defaults? (I have otherwise avoided these
to hopefully prevent unwanted / undocumented effects occuring on
development hardware running a full interface which may parse these)
I'd expect them to be overridden by any platform using them anyway.
Testing this with evtest on the board shows this:
kbingham@falcon-v3u:~$ sudo evtest /dev/input/by-path/platform-keys-event
Input driver version is 1.0.1
Input device ID: bus 0x19 vendor 0x1 product 0x1 version 0x100
Input device name: "keys"
Supported events:
Event type 0 (EV_SYN)
Event type 1 (EV_KEY)
Event code 2 (KEY_1)
Event code 3 (KEY_2)
Event code 4 (KEY_3)
Event type 5 (EV_SW)
Event code 0 (SW_LID) state 0
Event code 5 (SW_DOCK) state 0
