Add 'boot-hart-id' property to allow user to specify preferred cold boot HART for RISCV architecture in OpenSBI firmware.
If unspecified, the default lottery mechanism will be used to randomly select the cold boot hart.
This is mainly to solve some product requirements which a preferred cold boot hart is required.
