CubeMX 6.15.0 unnecessarily configures R1 pin in LTDC peripheral when using RGB666 Display

[Craig_Robertson]

For the STM32H743IIKx micro, CubeMX 6.15.0 unnecessarily creates a configuration for the R1 pin when creating an LTDC peripheral when using the RGB666 Display Type.

This should not be configured. The required R* pins for this Display Type are R2-R7, as per G2-G7 and B2-B7.

This did not occur in previous CubeMX versions, including 6.14.1.

This bug means that it is not possible to upgrade to this version of CubeMX with an existing project that already uses the pin(s) required for LTDC_R1.
