qcacmn: Use multi window write and read for pine

Write into hal register using three floating windows instead of one.
This change is done to avoid frequent window changes for writing into
DP and CE registers. Instead 3 windows are used. One window is statically
mapped to CE block and another window is mapped statically to DP block.
Due to this design there is no need to change the window register to
write into these blocks and write can be done on corresponding window
with single iowrite32. Similar loginc is used for ioread32.

Also modified the hp_addr and tp_addr in initialisation stage so that
hal_write will not have multiple if checks.
