Add command for getting ramsize in scripts

Link: https://lore.kernel.org/r/20260204184045.111808-1-linux@fw-web.de

Add a command for getting detected ram size with possibility to
assign it to an environment variable.

example usage:

BPI-R4> memsize
4096 MiB
BPI-R4> memsize memsz
BPI-R4> printenv memsz
memsz=4096
BPI-R4>

board with 8GB ram:

BPI-R4> memsize
8192 MiB
BPI-R4> memsize memsz
BPI-R4> printenv memsz
memsz=8192
BPI-R4>

Addresses above 4 GiB don't fit into 8 digits.
Use 13 digits which encompass up to 15 TiB.

The size of free memory should be $lmb_base - $ram_base.

Upcoming patches are mapping memory with RO, RW^X etc permsissions.
Fix the meminfo command to display them properly

Add the lmb records onto the end of the memory map.

U-Boot has a fairly rigid memory map which is normally not visible
unless debugging is enabled in board_f.c

Update the 'meminfo' command to show it. This command does not cover
arch-specific pieces but gives a good overview of where things are.

In preparation for expanding this command, move it into a separate file.
Rename the function to remove the extra underscore. Update the number of
arguments to 1, since 3 is incorrect.
