[PATCH v1 0/2] Add common wait_for_boot and reset_and_boot apis for cs35l41 drivers

[Stefan Binding <sbinding@opensource.cirrus.com>]

Both HDA and ASoC CS35L41 drivers use a similar meachnism for waiting
for the chip to boot: regmap_read_poll_timeout().
However, this method can break if the macro returns early if a
regmap_read() call fails.
Replace this macro with a loop which does not break on regmap_read()
failure.

In addition, ensure the software reset prior to boot does not fail,
and ensure it is additionally run in the ASoC driver.
