Subject: [PATCH v2 1/1] ARM: dts: hpe: BUG: Correct GXP register ranges

From: Charles Kearney <charles.kearney@....com>

Bug fix to correct memory ranges on GXP to include host registers. This 
corrects a issue where the host interrupt controller is not available.

Fixes: 53658de4fadb ARM: dts: Introduce HPE GXP Device tree

Signed-off-by: Charles Kearney <charles.kearney@....com>
