charger/isl9238c: enable slew rate control
Enable charge current and maximum system voltage slew rate control
on ISL9238C by default for better charger stability.
Since the control is only available on ISL9238C, not on A/B, and
there's no way to distinguish C and A/B in software side, introduce
a new config CONFIG_CHARGER_ISL9238C for 9238C users.
BUG=b:155366741
TEST=1) on asurada, verify the register configured correctly
2) verify the waveform looks better
