WSA881x version based register default values are
updated using regmap_register_patch() API, which
will bypass the cache. Fix this by enabling cache_only
flag before updating the register reset values.

Currently wsa881x default register table is defined for version 1.1.
Some of the default register values are different for version 2.0.
This change is to update default register values based on version.

Some of the Bongo read only registers are not set as
volatile. Because of this, register values are read
incorrectly when the driver reads these registers. Fix
this issue by updating read only registers as volatile.

wsa881x has inbuilt temperature sensor. Temperature sensor
is used for speaker protection and over temperature protection.
Add support for temperature sensor in wsa881x driver.
