schematic: mark R19 as dot no place

Browse Source

R19 pulls VCC_PHONE low for better power on detection.
but the voltage divider R20 + R21 also pull this line low using
a stronger pull down resistor ok 20 kOhm.
thus R19 is unnecessary-

this change has been tested with a real simtrace device.
trace and card emulation worked with a Nokia 3310.
