[2.0.x] VIKI2 & RE_ARM changes (#9686)

* VIKI2 & RE_ARM changes

1. Remove `DISABLED(SDSUPPORT)` from ST7565 in `ultralcd_impl_DOGM.h`. These LCDs share pins with the SD card and can run at the SD card rates.

2. Add SDSS definition to `pins_RAMPS_RE_ARM.h`.  Apparently the SDSS definition in `pins.h` is being processed before the one in `spi_pins.h` which resulted in not being able to read the SD card.
