Subject: [PATCH 1/2] arm64: dts: qcom: sa8775p: Fix the size of 'addr_space' regions

For both the controller instances, size of the 'addr_space' region should
be 0x1fe00000 as per the hardware memory layout.

Otherwise, endpoint drivers cannot request even reasonable BAR size of 1MB.

Cc: stable@...r.kernel.org # 6.11
