crypto: atmel-sha - correct the max burst size
The maximum source and destination burst size is 16
according to the datasheet of Atmel DMA. And the value
is also checked in function at_xdmac_csize of Atmel
DMA driver. With the restrict, the value beyond maximum
value will not be processed in DMA driver, so SHA384 and
SHA512 will not work and the program will wait forever.
So here change the max burst size of all the cases to 16
in order to make SHA384 and SHA512 work and keep consistent
with DMA driver and datasheet.
