[PATCH 0/2] arm64: alternative: Remove optional 'cfg' parameter

These patches remove the optional 'cfg' parameter from alternative
macros.

Use of the 'cfg' parameter is less clear than ifdeffery or IS_ENABLED()
checks, and also doesn't allow the compiler to elide asm() blocks when
'cfg' is not selected, so it's preferable to avoid it.

Mark.
