[PATCH v4 18/80] arm/kzm: drop RAM size fixup

[Igor Mammedov]

If the user provided too large a RAM size, the code used to
complain and trim it to the max size.  Now that RAM is allocated by
generic code, that's no longer possible, so generate an error and
exit instead.

v3:
 * rephrase commit message in nicer way
   ("Chubb, Peter (Data61, Kensington NSW)" <address@hidden>)
 * reword error message and use size_to_str() to pretty print suggested size
