* FuriHal: port spi to ll. Bootloader: add spi and display. * Makefile: rollback disabled freertos introspection * FuriHal: spi lock asserts. F6: minor cleanup port sdcard shenanigans to furi_hal_gpio. * SdCard: port missing bits to furi-hal-gpio * FuriHal: fix broken RX in SPI, update SPI API usage. RFAL: more asserts in SPI platform code. * GUI: clear canvas on start. FuriHal: no pullup on radio spi bus. * FuriHal: use check instead of assert in spi lock routines * FuriHal: remove timeouts * SdHal: add guard time to SDCARD CS PIN control. * FuriHal: proper name for SPI device reconfigure routine. SdHal: one more enterprise delay and better documentation. * Bootloader: update DFU text and add image. * FuriHal: drop unused ST HAL modules. * SdHal: fixed swapped hal_gpio_init_ex arguments * SpiHal: fixed swapped hal_gpio_init_ex arguments * IrdaHal: use hal_gpio_init instead of hal_gpio_init_ex * RfidHal: fixed swapped hal_gpio_init_ex arguments Co-authored-by: DrZlo13 <who.just.the.doctor@gmail.com>
