Defines prefixed with "CONFIG" should be limited to proper Kconfig options,
that are introduced in a Kconfig file.
Here, a definition for a bitmask to configure the SEND_ENABLE mode is named
CONFIG_SEND_ENABLE.
Rename this local definition to CONFIGURE_SEND_ENABLE to avoid defines
prefixed with "CONFIG".
No functional change.

The R-Car Gen3 rev. 2.30 Hardware User's Manual calls the bit "CCIE".
Hence if I would have written the driver, I would have used
#define PCIECCTLR_CCIE BIT(31) /* Configuration Send Enable */

Should I change it when I merge it ? That makes sense actually.

If I don't hear from anybody I will make the change above and merge it.
