Implement the following memmap variants: - memmap=nn[KMG]@ss[KMG]: force usage of a specific region of memory; - memmap=nn[KMG]$ss[KMG]: mark specified memory as reserved; - memmap=nn[KMG]: set end of memory.

Kernel doesn't care of memory region types, so drop the type field and don't pass it to add_sysmem_bank.
