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.

bios/sdram: add some margin on cdly ideal_delay, do the read_leveling even if write_leveling is not optimal.
...
We need to provide enough information to ease support and understand the issue. The write leveling/read leveling
are doing there best to calibrate the DRAM correctly and memtest gives the final result.
