Subject: [PATCH 1/1] ARM: Rename CONFIG_ARM_AMBA to CONFIG_ARM_PRIMECELL

The AMBA bus (Advanced Microcontroller Bus Architecture) is just an
interconnection bus that needs no software support.  Software support
offered in Linux is some sort of enumeration that only applies to
"PrimeCell" logic blocks (devices).  This renames the config option
to match reality.

Change suggested by Russell King.

Note: CONFIG_ARM_AMBA is retained and is enabled when
CONFIG_ARM_PRIMECELL is selected.  So any #ifdef in out-of-tree
drivers will still work until the symbol will be removed in due time.
