spi_flash: extend non-bitbanged flash support
...
This commit adds support for memory mapped writes
in the same configuration as memory mapped reads
are currently supported.
It also adds support for accessing registers
and erasing sectors in non-bitbanged single SPI
mode.

LiteSPI is not mature enough to be integrated in LiteX sim directly. (will case trouble is things are refactored).
This could be re-introduced later when more mature. For now simulation with LiteX Sim
