fsl_esdhc: Fix DMA transfer completion waiting loop
Rework the waiting for transfer completion loop condition
to continue waiting until both Transfer Complete and DMA End
interrupts occur. Checking of DLA bit in Present State register
looks not needed in addition to interrupts status checking,
so it can be removed from the condition. Also, DMA Error
condition is added to the list of data errors, checked in the loop.
