ASoC: arizona: Add output power up/down delays for speaker path
The later Arizona parts do run write sequences to power up and down the speaker path as such a delay needs to be inserted into the DAPM sequence to allow this to run. This patch adds appropriate delays into the existing coalesced delay scheme. Signed-off-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Signed-off-by: Mark Brown <broonie@kernel.org>
