commit b8ab62ff7199fac8ce27fa4a149929034fabe7f8 upstream.

According to arm cpus binding doc,
"
On 32-bit ARM v7 or later systems this property is
required and matches the CPU MPIDR[23:0] register
bits.

Bits [23:0] in the reg cell must be set to
bits [23:0] in MPIDR.

All other bits in the reg cell must be set to 0.
"

In i.MX7ULP, the MPIDR[23:0] is 0xf00, not 0, so fix it.
Otherwise there will be warning:
"DT missing boot CPU MPIDR[23:0], fall back to default cpu_logical_map"
