soc/intel/*: drop incomplete and unneeded check for DMI SRLOCK

Before enabling IO decode ranges, current code checks if the DMI SRLOCK
is set to prevent inconsistencies between LPC PCI cfg registers and LPC
DMI registers, when the latter are locked.

DMI SRLOCK only applies to PCHs with on-package DMI, but not to PCH-H,
PCH-S and others with discrete PCH packages. So this check is at least
incomplete.

Further, the lock gets applied by FSP and gets reset on a warm reset.
Thus, there is no case where the lock would be already set at the
places where the DMI registers get written currently.

Drop the checks for the reasons mentioned above.
