input: qpnp-power-on: use restart reason bits based upon PON GEN



Support using 7 bits in the SOFT_RB_SPARE PON register if the
PON peripheral is GEN2, otherwise use only 6 bits. This allows
compatibility with bootloader code on targets with older PMICs
where 7 bits for restart reasons are not necessary.
