staging: mt7621-pci: replace mdelay with msleep
There are two mdelay calls in driver code located in
'mt7621_pcie_reset_assert' and 'mt7621_pcie_reset_rc_deassert'
functions. Both of them are not called in an interrupt handler
nor holding any spinlock. Hence, the function mdelay in them
can be replaced with msleep, to reduce busy wait.
