soc/amd(MDN/PHX/Glinda): Update DISABLE_KEYBOARD_RESET_PIN help 

For MDN, PHX, & Glinda platforms, the Keyboard Reset functionality has
been moved from GPIO 129 to GPIO 21.

Additionally, the issue where the system would reset when the KBDRST_L
pin went low even when not configured for Keyboard reset seems to have
been fixed, so remove that text.
