LEON: added new drivers to the LEON2/LEON3 BSPs

Most drivers use the Driver Manager for device probing, they
work on AMBA-over-PCI systems if PCI is big-endian.

New APIs:
 * GPIO Library, interfaced to GRGPIO
 * GENIRQ, Generic interrupt service implementation helper

New GRLIB Drivers:
 * ACTEL 1553 RT, user interface is similar to 1553 BRM driver
 * GR1553 (1553 BC, RT and BM core)
 * AHBSTAT (AHB error status core)
 * GRADCDAC (Core interfacing to ADC/DAC hardware)
 * GRGPIO (GPIO port accessed from GPIO Library)
 * MCTRL (Memory controller settings configuration)
 * GRETH (10/100/1000 Ethernet driver using Driver manager)
 * GRPWM (Pulse Width Modulation core)
 * SPICTRL (SPI master interface)
 * GRSPW_ROUTER (SpaceWire Router AMBA configuration interface)
 * GRCTM (SpaceCraft on-board Time Management core)
 * SPWCUC (Time distribution over SpaceWire)
 * GRTC (SpaceCraft up-link Tele core)
 * GRTM (SpaceCraft down-link Tele Metry core)

GR712RC ASIC specific interfaces:
 * GRASCS
 * CANMUX (select between OCCAN and SATCAN)
 * SATCAN
 * SLINK
