cnss2: Update bound checks for sbl reg dumps to SRAM mem range

Add code to update the bound checks for sbl reg dumps to SRAM mem
range. Due to a firmware update, the sbl start address was moved
and the bound checks to dumps sbl reg failed. Update the bound
checks to SRAM mem range, so that any future update in firmware
would not impact SRAM dumps.
