software/liblitesdcard/spisdcard: simplify/rewrite for consistency with the others parts of the project.
...
- Improve code readability, remove un-needed or duplicate comments.
- Only use a spi_xfer function for both write/read.
- Set the SDCard to low clk freq before init and increase it when initialized.

64-bit support was added for 64-bit CPU because of limitation of the hardware
on CSR accesses. Now that the Wihhbone2CSR bus handles wishbone.sel, this is no
longer required.

soc/software/litesdcard: update for response register back to 128 bits
...
The additional (17th) byte returned via the response register was
ignored by software (bios and kernel), so LiteSDCard was updated
to only return the (original, useful) 128 bits.
This patch updates the LiteSDCard code in the LiteX bios to only
expect those 128 bits, and to do so in a manner that's portable
across CSR data widths and alignments.

wishbone/wishbone2csr: use wishbone.sel on CSR write.
...
CSR write is only done if wishbone.sel != 0. This should avoid the need for 64-bit
CSR alignment on 64-bit CPUs since a 64-bit Wishbone write access targeting only the
32-bit LSB or MSB will be splitted in 2x32-bit accesses: one with sel=0xf, one with sel=0.
