ARM: dts: BCM5301X: Fix I2C controller interrupt
[ Upstream commit 754c4050a00e802e122690112fc2c3a6abafa7e2 ]
The I2C interrupt controller line is off by 32 because the datasheet
describes interrupt inputs into the GIC which are for Shared Peripheral
Interrupts and are starting at offset 32. The ARM GIC binding expects
the SPI interrupts to be numbered from 0 relative to the SPI base.
