Missing define for SPI6I2S on STM32H7

S58D4J

Some STM32H7 MCUs have I2S capability on SPI6, but the HAL does not define "SPI_SPI6I2S_SUPPORT" for all of them. The ones with the missing define gets the prescaler computed wrong if the clock for SPI123 and SPI6 is different.

 

Has HAL support:

H7B3
H7B0
H7A3

 

Has capability but missing HAL support:
H735
H733
H730
H725
H723

 

Manually adding the define fixes the issue, the prescaler is calculated correctly and the expected clock frequency is sent to the I2S pins.
