Documentation/kernel-parameters.txt: Update 'memmap=' boot option description
In commit:
9710f581bb4c ("x86, mm: Let "memmap=" take more entries one time")
... 'memmap=' was changed to adopt multiple, comma delimited values in a
single entry, so update the related description.
In the special case of only specifying size value without an offset,
like memmap=nn[KMG], memmap behaves similarly to mem=nn[KMG], so update
it too here.
Furthermore, for memmap=nn[KMG]$ss[KMG], an escape character needs be added
before '$' for some bootloaders. E.g in grub2, if we specify memmap=100M$5G
as suggested by the documentation, "memmap=100MG" gets passed to the kernel.
Clarify all this.
