[PATCH] x86/microcode: add parameter dis_ucode_ldr in kernel-paramenters.txt

[Fenghua Yu]

From: Fenghua Yu <fenghua.yu@xxxxxxxxx>

The kernel parameter dis_ucode_ldr disables early loading microcode from
initrd. The parameter was introduced earlier by Borislave Petkov.

This patch adds the explanation for this parameter in
Documentation/kernel-parameters.txt for user convenience.
