TEMP: NOT FOR REVIEW: Use absolute jump address

When the qcs405 soc jumps from qc_sec to bootblock,
the pc is at 0x0 address mapped to actual SRAM address(0x8c30000).
The mapping happens in a hardware block 'boot-remapper'
only for a maximum of 128K possible.
If the bootflow continues from the 0x0 address,
bootblock references variable beyond 128K crashing the boot.

So change the PC to start execting from the absolute address
instead.
