[PATCH v3 2/2] spi: dt-bindings: spi-controller: Fix spi-[rt]x-bus-width for slave mode

[Geert Uytterhoeven <geert+renesas@xxxxxxxxx>]

The descriptions for the spi-rx-bus-width and spi-tx-bus-width
properties refer to "MISO" and "MOSI", which are not explained in the
document.  While these abbreviations are fairly common when talking
about SPI, and thus may not need an explanation, they are not entirely
correct in this context, as the SPI controller may be used in slave mode
instead of master mode.

Fix this by replacing them by "read transfers" resp. "write transfers",
like is done for the spi-rx-delay-us and spi-tx-delay-us properties.

v3:
  - No changes,

v2:
  - New.

This issue was present in the .txt version of the bindings, too, so
technically it needs
Fixes: a8830cb19cfea04e ("spi: Document DT bindings for SPI controllers in slave mode")
but of course it won't apply to that version.
