ARM: dts: msm: modify charging LED configuration for msm8998 MTP/QRD

Currently, red and green LEDs are used for showing charging and
full status. Since they're configured with battery-charging and
battery-full LED triggers, power supply framework updates these
LEDS for battery power supply based on charging status. Remove
these default trigger configurations so that these LEDs can be
controlled by userspace in a better way. Also, specify blinking
configuration for red LED so that it can be used for indicating
HVDCP chargers.
