[PATCH] media: ttpci: build av7110_ir.c only when allowed by CONFIG_INPUT_EVDEV

[Randy Dunlap <rdunlap@infradead.org>]

From: Randy Dunlap <rdunlap@infradead.org>

Fix build when CONFIG_INPUT_EVDEV=m and DVB_AV7110=y.
Only build av7110_ir.c when CONFIG_INPUT_EVDEV is compatible with
CONFIG_DVB_AV7110.

Fixes these build errors:

drivers/built-in.o: In function `input_sync':
av7110_ir.c:(.text+0x1223ac): undefined reference to `input_event'
drivers/built-in.o: In function `av7110_emit_key':
