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

Commit Message

From: Nick Hawkins <[e-mail]>

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.
