Binding documentation: - Add future-proof "renesas,msiof-<soctype>" compatible values, - Add example bindings. Implementation: - MSIOF on R-Car H2 and M2 requires the transmission of dummy data if data is being received only (cfr. "Set SICTR.TSCKE to 1" and "Write dummy transmission data to SITFDR" in paragraph "Transmit and Receive Procedures" of the Hardware User's Manual). - As RX depends on TX, MSIOF on R-Car H2 and M2 also lacks the RSCR register (Receive Clock Select Register), and some bits in the RMDR1 (Receive Mode Register 1) and TMDR2 (Transmit Mode Register 2) registers. - Use the recently introduced SPI_MASTER_MUST_TX flag to enable support for dummy transmission in the SPI core, and to differentiate from other MSIOF implementations in code paths that need this. - New DT compatible values ("renesas,msiof-r8a7790" and "renesas,msiof-r8a7791") are added, as well as new platform device names ("spi_r8a7790_msiof" and "spi_r8a7791_msiof"). - Hardware features are indicated using a new struct sh_msiof_chipdata, which is used for both DT and legacy binding. For now this contains the SPI master flags only. This is loosely based on a set of patches from Takashi Yoshii <takasi-y@ops.dti.ne.jp>.
