HV: add memmap param for hvlog in sos cmdline

Browse Source 
Reserve memory for hv sbuf to avoid its possible overwriting on kernel memory.

For apl-up2, move hv_log address to 0x5de00000 to avoid possible conflict with
HV_RAM which start from 0x5e000000;

For nuc6cayh, move HV_RAM_START to 0x20000000 to avoid possible conflict with
hv_log which start from 0x1fe00000;

Tracked-On: #3533
