Subject: [PATCH] mfd: davinci_voicecodec: remove pointless #include
Date:   Fri, 28 Jun 2019 12:41:22 +0200

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.
