The base address of JPEG decoder core 1 should start at 0x10000, and
have a size of 0x10000, i.e. it is right after core 0.

Instead the core has  the same base address as core 0, and with a crazy
large size. This looks like a mixup of address and size cells when the
ranges were converted.

This causes the kernel to fail to register the second core due to sysfs
name conflicts:

    sysfs: cannot create duplicate filename '/devices/platform/soc/soc:jpeg-decoder@1a040000/1a040000.jpgdec'

Fix up the address range.
