mfd: davinci_voicecodec: Remove pointless #include

When building davinci as multiplatform, we get a build error
in this file:

drivers/mfd/davinci_voicecodec.c:22:10: fatal error: 'mach/hardware.h' file not found

The header is only used to access the io_v2p() macro, but the
result is already known because that comes from the resource
a little bit earlier.
