Add USART6 pins to MKS TFT35 V1.0 variant so it doesn't fall back to the incorrect defaults

Requirements

MKS TFT35 V1.0 Touch screen

Description

Add USART6 pins to MKS TFT35 V1.0 variant so it doesn't fall back to the incorrect defaults. The TFT uses the STM32F407VET6 MCU in a 100 pin package. (https://github.com/makerbase-mks/MKS-TFT-Hardware/blob/master/MKS%20TFT35/MKS%20TFT35%20V1.0_003/MKS%20TFT35%20V1.0_003%20SCH.pdf).
So the correct USART6 pins are:
USART6_TX_PIN PC6
USART6_RX_PIN PC7

Confirmed on the actual hardware.

Benefits

Working USART6 serial communication
