media: v4l: cci: Add macros to obtain register width and address

Browse source

[ Upstream commit cd93cc245d ]

Add CCI_REG_WIDTH() macro to obtain register width in bits and similarly,
CCI_REG_WIDTH_BYTES() to obtain it in bytes.

Also add CCI_REG_ADDR() macro to obtain the address of a register.

Use both macros in v4l2-cci.c, too.
