[PATCH 6.19 154/781] arm64: dts: qcom: sdm850-huawei-matebook-e-2019: Correct ipa_fw_mem for the driver to load successfully

From: Jingzhou Zhu <newwheatzjz@zohomail.com>

[ Upstream commit bc11f6f1d2470fa59846be077555f9d4b7c2c0d3 ]

The ipa driver refuses to load with the old ipa_fw_mem in newer kernels.
Shrinking its size to 0x5a000 fixes the problem.

Fixes: aab69794b55d ("arm64: dts: qcom: Add support for Huawei MateBook E 2019")
