Revert "LF-6630-1 mailbox: imx: clear pending interrupts"
With MCU SDK supports multiple vring instance, after Linux clear
GIP & RSR for the 1st vring instance, MCU SDK will continue issue
GIP & VQID for the next vring instance, we could not handle multiple
vring instance in mailbox driver.
This reverts commit a53f2179ef57d5f6bd9a4e0d9be2f602df3e1f89.
