The si476x_core_get_revision_info will send i2c command to FM module, if it
return error, there is no FM modules attached, so we need't to register the
sound card. otherwise, the pulseaudio will access this sound card, but return
a lot of i2c error.

Currently, si476x-rev1.0 and si476x-rev4.0 board just support A10 compatible
command set. For si476x-rev1.0 board, its firmware revision is unsupported and
will revert to A10 compatible function. For si476x-rev4.0 board, its firmware
revision is two and will use A30 function, but A30 command set function can't
work for the rev4.0 board.
So make the command set configurable in dts. If "revision-a10" is present,
set the revision to SI476X_REVISION_A10 to use A10 compatible commit set.
Otherwise, get the revision from si476x register.

Since commit 1c6c69525b40eb76de8adf039409722015927dc3 ("genirq: Reject
bogus threaded irq requests") threaded IRQs without a primary handler
need to be requested with IRQF_ONESHOT, otherwise the request will fail.
So pass the IRQF_ONESHOT flag in this case.
The semantic patch that makes this change is available
in scripts/coccinelle/misc/irqf_oneshot.cocci.
