[patch V2 06/37] x86/microcode/intel: Rename get_datasize() since its used externally

[Thomas Gleixner <tglx@linutronix.de>]

From: Ashok Raj <ashok.raj@intel.com>

Rename get_datasize() to intel_microcode_get_datasize() and make it an inline.

[ tglx: Make the argument typed and fix up the IFS code ]
