max77759_charger: remove MAX77759_CHG_INT_MASK_CHG_M

MW keeps switching between CC and CV when input current limited
in CV stage. This generates a lot of unwanted power supply event
notifications. Mask CC/CV interrups and restrict the type of
interrupt that generates power supply events to BATTERY, CHGIN,
WLCIN.

Bug: 191405477
Test: wired, wireless charge start and stop. EOC behavior, dc start stop.
