gsp-phys: use the 4-entry GP10X root format for the VAS page directory
The TU104 GMMU root level has 2 index bits (4 PDEs of 2^47 bytes each), so
the server's vaLimitNew = (numEntries << 47) - 1 must stay within its
vaLimitMax = 2^49-1; numEntries=256 computed 2^55-1 and drew
NV_ERR_INVALID_ARGUMENT (0x1f). Send 4 entries (32 bytes of the 4 KB
page-aligned VASPDB chunk) and log the value on failure. The aperture/flags
word is unchanged (0x0a, SYSMEM_NONCOH + ALL_CHANNELS).
