Due to IP integration difference, there are 2 ahb irqs
for imx6 and only 1 ahb irq for imx8. This patch makes
mlb driver compatible with irq difference.

As a result that the wrong operation is used for the mlb status
in mlb_isr(), some results are independent of their operations.
for example:
rx_cis = (cdt_val[2] & ~MASK) >> SHIFT, where, MASK = 0xf0000000
and SHIFT = 28. So, the result is always 0 regardless of the values
of its operands.
This patch fixes the operation for mlb status in mlb_isr().
