Greg, do you see any obstacle to have this merged. The discussion so far
shown that a) vendors are not using the code as is b) there seems to be
an agreement that something else than we have in the kernel is really
needed.

This is quite simple. For the first one, it doesn't seem that it's
DMA'd into, so there's no need to use GFP_DMA.

arizona_poll_reg essentially hard-codes regmap_read_poll_timeout, this
patch updates the implementation to use regmap_read_poll_timeout. We
still keep arizona_poll_reg around as regmap_read_poll_timeout is a
macro so rather than expand this for each caller keep it wrapped in
arizona_poll_reg.

arizona_poll_reg already returns ETIMEDOUT if we don't see the expected
register changes before the time out, so remove pointless local setting of
ETIMEDOUT.

Sata ecc is controlled by only 1 bit which is 24bit in big-endian
in ecc register. So only setting 24bit to disable sata ecc prevents
other bits from being overwritten in ecc register.

Currently, we specify the timeout in terms of the number of polls but it
is more clear from a user of the functions perspective to specify the
timeout directly in milliseconds, as such update the function to these new
semantics.
