[PATCH v1 1/1] ARM: dts: hpe: Correct GXP register ranges

[nick.hawkins at hpe.com]

From: Nick Hawkins <nick.hawkins at hpe.com>

Correct memory ranges on GXP to include host registers. This corrects a
issue where the host interrupt controller is not available. Additionally
there is a large gap of reserved registers that will not be used. To avoid
this area two ranges are used.
