ASoC: codecs: wcd9335: Fix missing free of regulator supplies

In the Linux kernel, the following vulnerability has been resolved:

ASoC: codecs: wcd9335: Fix missing free of regulator supplies

Driver gets and enables all regulator supplies in probe path
(wcd9335_parse_dt() and wcd9335_power_on_reset()), but does not cleanup
in final error paths and in unbind (missing remove() callback).  This
leads to leaked memory and unbalanced regulator enable count during
probe errors or unbind.

Fix this by converting entire code into devm_regulator_bulk_get_enable()
which also greatly simplifies the code.

CWE-416 Use After Free

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
