[PULL v2 27/32] hw/riscv: sifive_u: Add a new property msel for MSEL pin state |

From: Bin Meng <bin.meng@windriver.com>
On SiFive FU540 SoC, the value stored at physical address 0x1000
stores the MSEL pin state that is used to control the next boot
location that ROM codes jump to.
Add a new property msel to sifive_u machine for this.
