spi: stm32: add a delay before SPI disable
[ Upstream commit 6de8a70c84ee0586fdde4e671626b9caca6aed74 ]
As explained in errata sheet, in section "2.14.5 Truncation of SPI output
signals after EOT event":
On STM32MP1x, EOT interrupt can be thrown before the true end of
communication.
So we add a delay of a half period to wait the real end of the
transmission.
