[PATCH -next] platform: x86: fix silead_dmi build error and depends

[Randy Dunlap]

From: Randy Dunlap <rdunlap@infradead.org>

This driver cannot be built as a loadable module, so it should not
be built unless I2C=y and INPUT=y.

Fixes this build error:
drivers/built-in.o: In function `silead_ts_dmi_init':
silead_dmi.c:(.init.text+0xf00e): undefined reference to `i2c_bus_type'

I don't see why the "depends on INPUT" was there at all,
but I modified its requirement anyway.  Maybe it can be removed...

Thank you for catching this. However the depends on INPUT is not
necessary at all (likely a copy and paste error during development)
can you please do a v2 dropping the input dependency all together ?

Regards,

Hans
