arm64: versal: Fix LTO for mini_ospi/mini_qspi
With LTO enabled, mini U-Boot was hanging during reloc_fdt().
The initial stack pointer was placed too low, and the FDT memcpy
destination was carved only 4KB above it. This left insufficient
margin, causing the FDT copy to overwrite the live early stack
and corrupt execution before relocation.
To fix this, increase the malloc heap from 8KB to 12KB and raise the
initial stack pointer by 4KB. Together these adjustments increase
the separation between the early stack and the FDT region during
the pre-relocation phase, eliminating the overlap and fixing the
hang on mini builds (QSPI/OSPI).
