pinctrl: mediatek: mt7986: register both platform drivers from a single initcall

The MT7986 driver registers two separate platform drivers (mt7986a and
mt7986b) and used to call arch_initcall() twice, once for each.

This is fine while the driver is built-in, but a single translation unit
can only provide one module_init(). Since arch_initcall() expands to
module_init() when built as a module, having two of them would break the
module build with a redefinition of init_module()/__inittest().

Fold both platform drivers into a single driver array and register them
from one initcall using platform_register_drivers(), matching the shape of
the other MediaTek pinctrl SoC drivers. platform_register_drivers() also
rolls back the first registration if the second one fails.

No functional change for built-in builds; this is a preparatory cleanup
for enabling module builds.
