SLIMbus supports upto 16 bytes in value management messages,
so add support to read/writes upto 16 bytes.
This also removes redundant single register reg_read/reg_write.
Also useful for paged register access on SLIMbus interfaced codecs.

As per SLIMBus specs Value Elements and Information Elements
address map ranges from 0x000 - 0xFFF.
So allow register addresses up to 16 bits

This patch adds support to read/write SLIMbus value elements.
Currently it only supports byte read/write. Adding this support in
regmap would give codec drivers more flexibility when there are more
than 2 control interfaces like SLIMbus, i2c.
Without this patch each codec driver has to directly call SLIMbus value
element apis, and this could would get messy once we want to add i2c
interface to it.
