Currently pl330 use single mode defaultly. But burst
mode can improve efficiency of memory accessing. We
couldn't enable it by defalut in case of breaking any
Socs which don't support it.

With burst mode supported, we could see the improvement
significantly when tesing SPI transfer etc.

default single mode
[   88.292550] spi write 65536*1 cost 32402us speed:2022KB/S

After applied with burst mode(len 16)
[   17.625296] spi write 65536*1 cost 17830us speed:3675KB/S
