Subject: [PATCH V3 08/10] can: flexcan: rename macro FLEXCAN_QUIRK_SETUP_STOP_MODE -> FLEXCAN_QUIRK_SETUP_STOP_MODE_GPR

This patch intends to rename FLEXCAN_QUIRK_SETUP_STOP_MODE quirk
to FLEXCAN_QUIRK_SETUP_STOP_MODE_GRP for non-scu SoCs, coming patch will
add quirk for scu SoCs.

For non-scu SoCs, setup stop mode with GPR register.
For scu SoCs, setup stop mode with SCU firmware.
