opal-prd: Fix prd message size issue
If prd messages size is insufficient then read_prd_msg() call fails with
below error. And caller is not reallocating sufficient buffer. Also its
hard to guess the size.
sample log:
-----------
Mar 28 03:31:43 zz24p1 opal-prd: FW: error reading from firmware: alloc 32 rc -1: Invalid argument
Mar 28 03:31:43 zz24p1 opal-prd: FW: error reading from firmware: alloc 32 rc -1: Invalid argument
Mar 28 03:31:43 zz24p1 opal-prd: FW: error reading from firmware: alloc 32 rc -1: Invalid argument
....
Lets use `opal-msg-size` device tree property to allocate memory
for prd message.
