Rename lspcon_i2c_spi to parade_lspcon

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.

https://www.paradetech.com/products/ps175/
https://www.acer.com/ac/en/US/content/series/acerchromeboxcxi4

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