refactor: SD card SPI HAL (#3957)

* refactor: SD card SPI driver

* Removed SPI and DMA StdPeriph drivers

* Allow for disabling SPI DMA support

* Disable SPI sdcard CRC support

* Fix 2MHz timer on NV14

* Shared VS1053b driver

* Fix: SPI2 uses PCLK1

* feat: new generic diskio API

* More generic SD_CARD_PRESENT()

* Fixes

* Flush incoming block on token mismatch

* Scratch buffer test

* Incredible hack to re-sync sd card

* fix: SDIO driver
