mb/*/brya/variants/brask: Enable dynamic GPIO PM

GPIO PM was disabled for brask to evaluate if longer interrupt pulses
are required for ADL. Since ADL requires 4us long pulses (EDS:626817),
GPIO PM can be enabled. This change drops the GPIO PM override and
re-enables dynamic GPIO PM.

TEST=Boot brask to OS, ensure no TPM errors.
