[U-Boot] [PATCH 1/6] sf: Simplify fastest read cmd code
Fastest read command code look for fastest read command taking inputs from spi->mode_rx and flags from param table and controller mode_rx is always been a priority.
Since mode_rx is always set from controller side this optimized code doesn't require much and this code required exctra overhead like 1) Maintain e_rx_cmd in param table 2) Maintain mode_rx in spi_slave {}
Hence removed this code, and look for read command from normal spi->mode from spi_slave{} and params->flags

e_rd_cmd is maintained separately for fastest read command code, since the read commands are computed normally this e_rd_cmd is not required in spi_flash_params table.
