arm64: zynqmp: Fix SVD mask for getting chip ID

Mask should start from the first bit - using 0xe is just wrong.
3bits are used that's why 0x7 mask is correct.
This patch is fixing silicon ID code detection. Previous behavior was
that bit0 was completely ignored.
Issue was found on 2eg chip detection.
