ASoC: wm8962: Add an event handler for TEMP_HP and TEMP_SPK
In wm8962 driver, the WM8962_ADDITIONAL_CONTROL_4 is used as a volatile
register, but this register mixes a bunch of volatile status bits and a
bunch of non-volatile control bits. The dapm widgets TEMP_HP and
TEMP_SPK leverages the control bits in this register. After the wm8962
probe, the regmap will bet set to cache only mode, then a read error
like below would be triggered when trying to read the initial power
state of the dapm widgets TEMP_HP and TEMP_SPK.
wm8962 0-001a: ASoC: error at soc_component_read_no_lock
on wm8962.0-001a: -16
In order to fix this issue, we add event handler to actually power
up/down these widgets. With this change, we also need to explicitly
power off these widgets in the wm8962 probe since they are enabled
by default.
