Clarify that SWSPI_WDATA_* coincidentally uses the same
commands as specified by JEDEC.
A similar data sheet does not really shed light if these
literally are raw JEDEC command values or 'virtual' ones.
As to avoid confusion, comment but perhaps not use the JEDEC
literals from spi.h until it is certain.

Currently i2c programmers do not have a safe allow listing
mechanism via board_enable to facilitate fully qualified
chip detection.
Since i2c addresses alone can overlap a user may make the mistake
of using the wrong programmer. Although unlikely, it is within the
realm of possibility that a user could accidently somehow program
another chip on their board.

The chip targeted by the `lspcon_i2c_spi` programmer is a Parade PS175.
Rename the programmer to match the chips vendor / family instead of the
generic LSPCON protocol. Remove the `_i2c_spi` ending in preparation to
become an opaque master. The chip is visible on an Acer Chromebox CXI4.

TEST: `make CONFIG_PARADE_LSPCON=yes` and
`meson build -Dconfig_parade_lspcon=true` produces flashrom
binaries with the parade_lspcon programmer included.
