lib: Rewrite qemu-armv7 ramdetect
* Move armv7 RAM dection to a common place
* Enable it for all emulated platforms
* Use 32bit probe values and restore memory even on failure
* Use the new logic on the following boards:
** qemu-armv7
** qemu-riscv
Tested on qemu-system-riscv:
Fixes kernel panic due to wrong memory limits reported.
