This patch introduces the use of IS_ENABLED() macro. For example,
replacing:
 #if defined(CONFIG_I2C) || (defined(CONFIG_I2C_MODULE) && defined(MODULE))
with:
 #if IS_ENABLED(CONFIG_I2C)
All changes made by this patch respect the same replacement pattern.

The current test doesn't make a lot of sense.  It's likely to be true,
which is what we would want in most cases.  From looking at how this is
handled in other drivers,  I think "&" was intended instead of "*".
It's an easy mistake to make because they are next to each other on the
keyboard.

We already have the key polling functions and the polling infrastructure in
em28xx-input, so we can easily get rid of the dependency on module ir-kbd-i2c.
For maximum safety, do not touch the key reporting mechanism for those devices.
Code size could be improved further but would have minor peformance impacts.
Tested with device "Terratec Cinergy 200 USB" (EM2800_BOARD_TERRATEC_CINERGY_200)

Change several memcpy() to memmove() in cases when the regions are
definitely overlapping; memcpy() of overlapping regions is undefined
behavior in C and can produce different results depending on the compiler,
