[HAL][LPC176x] Pull out framework into separate repository
Framework and build platform now located at https://github.com/p3p/pio-framework-arduino-lpc176x and https://github.com/p3p/pio-nxplpc-arduino-lpc176x respectively fix mkssbase leds move hardware serial remove hardware/software serial Hardware Serial extraction HardwareSerial ISRs fix disabled serial2 causing Serial object to link move usb devices out to framework separate out adc/pwm peripheral function from hal.cpp fix includes remove unused pwm init move adc HAL header update templated filtered adc LPC1769 platform
