This adds new NXP mailbox driver for MBOX device.
NXP mailbox IP driver supports sending data between cores.
It uses 32 bit register to trigger irq to other core.
This driver implementation uses 4 bits for channel selection of
triggering mode, 4 bits for channel selection of data transfer and
rest 24 bits for data.
