PCI: rcar: Avoid defines prefixed with CONFIG
Defines prefixed with "CONFIG" should be limited to proper Kconfig options,
that are introduced in a Kconfig file.
In the R-car driver the bitmask to configure the SEND_ENABLE mode is named
CONFIG_SEND_ENABLE.
Rename this local definition to a more suitable name, containing the
register bitfield name defined in the R-Car Gen3 rev. 2.30 user
manual.
No functional change.
