Start using __free() and guard() primitives to simplify the code

handling more robust by ensuring that locks are released in all
code paths when control leaves critical section and all allocated

Extend the novatek touchscreen driver to support NT36672A chip which
is found in phones like qcom/sdm845-xiaomi-beryllium-tianma.dts.
Added devicetree support for the driver and used i2c chip data to handle
the variation in chip id and wake type. Also added vcc and iovcc
regulators which are used to power the touchscreen hardware.

There's no need to get the length of an DT array property before
parsing the array. of_property_read_variable_u32_array() takes a
minimum and maximum length and returns the actual length (or error
code).
This is part of a larger effort to remove callers of of_get_property()
and similar functions. of_get_property() leaks the DT property data
pointer which is a problem for dynamically allocated nodes which may
be freed.
