fix(board): update spi_id max for sgi multichip platforms

Browse source 
According to GIC-600 TRM, 960 SPIs could be supported on a platform.
However, with the current configuration, platforms such as RD-V1-MC and
RD-N1-Edge Dual-Chip utilize a much smaller range. With commit
'a02a45dfe' gic600 driver is updated to get the max SPI id from the
GIC-600 and probe for the corresponding GIC instance for each SPI id.
Since RD-V1-MC and RD-N1-Edge Dual-Chip supports wider range, increase
SPI range for the chip 0 to max SPI range supported.
