STM32G4 SPI4 has swapped reset values for CR1 and CR2

[techmccat]

I notieced while looking at the g474 svd files because svd2rust had created different modules for spi1 and spi4, despite the manual not saying anything about different registers.

spi2 and spi3 are affected too since they re-export spi4.
Fixing this difference could also allow all the spi peripheral to share RegisterBlock definition (thus implementing Deref for the same type)

Register definitions are on page 1787 of the g4 manual found here
Here's the diff of the peripheral definitions I manually copy-pasted from the svd
