lib: ramdetect: Add Kconfig PROBE_RAM
Previously ramdetect.c was compiled only for VENDOR_EMULATION.
Hence add Kconfig option PROBE_RAM which allows board outside
the scope of VENDOR_EMULATION to select and utilize probe_ram
function to runtime detect usable RAM in emulation environment.
PROBE_RAM is default selected if VENDOR_EMULATION is set so
that existing boards under VENDOR_EMULATION scope are not
affected.
Other boards can explicitly select PROBE_RAM to use probe_ram.
TEST=Build mb/arm/rdn2 with PROBE_RAM selected & make sure
there is no any error.
Also checked qemu-aarch64 build to make sure build is success.
