meta-agl-bsp: extend qemux86-64 hardware support

Copy extra hardware support kernel configuration fragments used with
meta-intel for intel-corei7-64 machine over to also use them with
qemux86-64, and add apparently now required LPSS configuration
options to x86-upsquared.cfg to fix serial console support.
