powerpc/85xx: Create dts of each core in CAMP mode for P1020RDB 



Create the dts files for each core and splits the devices between the two
cores for P1020RDB.

Core0 has core0 to have memory, l2, i2c, spi, gpio, tdm, dma, usb, eth1,
eth2, sdhc, crypto, global-util, message, pci0, pci1, msi.
Core1 has l2, eth0, crypto.

MPIC is shared between two cores but each core will protect its interrupts
from other core by using "protected-sources" of mpic.

Fix compatible property for global-util node of P1020si.dtsi.

/*

 * P1020 RDB  Core0 Device Tree Source in CAMP mode.

 *

 * In CAMP mode, each core needs to have its own dts. Only mpic and L2 cache

 * can be shared, all the other devices must be assigned to one core only.

 * This dts file allows core0 to have memory, l2, i2c, spi, gpio, tdm, dma, usb,

 * eth1, eth2, sdhc, crypto, global-util, message, pci0, pci1, msi.

 *

 * Please note to add "-b 0" for core0's dts compiling.
