From: Peng Fan <peng.fan@nxp.com>
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"
