The GXP SoC supports 10 I2C engines. Each I2C engine is completely
independent and can function both as an I2C master and I2C slave. The
I2C master can operate in a multi master environment. The engines support
a scalable speed from 8kHZ to 1.5 Mhz.

Changes since v1:
*Removed yaml documentation of hpe,gxp-sysreg as it has been
applied to syscon.yaml
*Made i2cX a generic node name i2c in dts file
*Added status field to the dtsi and the dts for i2c bus
*Removed unnecessary size-cells and address-cells from yaml
*Removed phandle from hpe,sysreg-phandle
*Changed hpe,i2c-max-bus-freq to clock-frequency
*Removed rogue tab in structure definition
*Removed use of __iomem *base local variables as it was
unnecessary
*Switched #if IS_ENABLED() -> if (IS_ENABLED()) inside
functions
*Removed use of pr_* functions
*Removed informational prints in register and unregister
functions
*Removed print from interrupt handler
*Removed informational prints from probe function
*Switched dev_err -> dev_err_probe in probe function
*Used the respective helper for mapping the resource to
__iomem

Apologies. This was in error.
