boards: infineon: cyw20829m2evk_02: update memory partitions map

With current memory map configuration we have build error
with some samples where enabled no_optimization option.

So update memory partitions map as following:

ram:
sram:            : 244k  (addr 0x20000000)
sram_bootstrap   : 12k   (addr 0x2003D000)

flash:
toc2_region      : 80b   (addr 0x60000000)
bootstrap_region : 12k   (addr 0x60000050)
app_region       : 435k  (addr 0x60003050)
storage_partition: 64k   (addr 0x60070000)
