Input: sirfsoc-onkey - allow modular build
CONFIG_INPUT may itself be a loadable module, but the sirf power key
driver is listed as 'bool', which makes it possible to select
a broken configuration with the driver built-in but the subsystem
not loaded. In this configuration, we get a link error:
drivers/input/built-in.o: In function `sirfsoc_pwrc_isr':
drivers/input/misc/sirfsoc-onkey.c:63: undefined reference to `input_event'

drivers/input/built-in.o:(.debug_addr+0x128): undefined reference to `input_register_device'
This marks the driver as 'tristate' so it becomes possible to have
it in a loadable module, mainly to help with randconfig builds.
We also have to add a missing semicolon here, which ended up not
being needed in built-in mode because the following MODULE_DEVICE_TABLE
is an empty macro followed by another semicolon then.
