soc: qcom: User resource pair number correctly

The number of resource pairs conveyed by the HW starts at 0, i.e a
value of 0x0 indicate 1 resource pair, 0x1 indicate two and so on.
As such add 1 to the value of NUMRSPAIR for a better representation.
Multiple 2 in save and restore operattion since it's number of pairs.
