ENGR00315894-60 GPIO: Modify driver mxc_gpio to support RDC Semaphores
For GPIO group which shared by multiple masters, it may set in RDC
to shared and semaphore required. Before access the GPIO register,
the GPIO driver must get the RDC semaphore, and release the semaphore
after the GPIO register access.
When CONFIG_MXC_RDC is set, the features related to RDC semaphores
is enabled in mxc_gpio driver.
