platform/x86: int3472: Make regulator supply name configurable

This is a preparation patch for registering multiple regulators, which
requires a different supply-name for each regulator. Make supply-name
a parameter to skl_int3472_register_regulator() and use con-id to set it
so that the existing int3472_gpio_map remapping can be used with it.

Since supply-name is a parameter now, drop the fixed
skl_int3472_regulator_map_supplies[] array and instead add lower- and
upper-case mappings of the passed-in supply-name to the regulator.
