LEON: updated and added PCI peripherals for LEON BSPs

The CCHIP driver is replaced with the GR_701 driver. The
RASTA driver is replaced by the GR-RASTA-IO driver.

All drivers are now compatible with both LEON2 and LEON3,
drivers were initialized directly by the PCI-board drivers
are now initialized by the driver manager and therefore
does not require the double code created by including for
example grcan.c into grcan_rasta.c. The other drivers needs
to be updated to the driver manager framework however.

Added support for:
 * GR-701 (only LEON2 before)
 * GR-RASTA-IO (only LEON2 before)
 * GR-RASTA-ADCDAC
 * GR-RASTA-TMTC
 * GR-RASTA-SPW-ROUTER
 * GR-TMTC-1553
