boards: rddrone_fmuk66: correct pinmux errors

Browse source 
Correct the following errors in rddrone pinmux:
- Pin selection for UART4 RTS line was incorrect, should use PTE27
- Pin selection for red PWM LED was incorrect, should use PTD1
- FlexCAN0/1 RX should not have pullup resistors (per prior pinmux.c
settings)
- FTM0_CH1_PTA4 does not require a pullup resistor
- LPUART0_RX_PTD8 requires a pullup resistor for UART RX to work

Fixes #44314
