This patch series makes some initial minor and cosmetic changes:
-Add variables and logic to handle separate source and destination
AxSize and AxLen.
-Use __ffs to calculate AxSize for consistency in the driver
-Use switch-case in prep_slave_sg() for consistency
-Change args get_burst_len() to remove redundant "len" and add
burst_size so that it can be used in multiple places.
to majorly enable addition of 2 logical changes in the last 2 patches:
-Allow transactions towards memory to use the maximum possible
bus width (AxSize) during a memory to peripheral dma usage or
vise-versa.
-Add logic to copy left over data after executing bursts to
the peripheral in singles instead of bursts.
