ARM: dts: bcm63148: Add I2C block

Browse Source 
The BCM63148 has a brcmper I2C block.

The peripheral range needs to be extended to accommodate
it. The Boot LUT is at offset + 0x10000 so extend it to
cover at least that too, 128 KB.

INTERRUPT_ID_I2C is at (ISR_TABLE3_OFFSET + 19) = 96+19 = 115,
convert back to SPI IRQ 115-32 = 83.
