Heiko Stuebner 5e9c68ea77 RISC-V: Cache SBI vendor values ... sbi_get_mvendorid(), sbi_get_marchid() and sbi_get_mimpid() might get called multiple times, though the values of these CSRs should not change during the runtime of a specific machine. Though the values can be different depending on which hart of the system they get called. So hook into the newly introduced cpuinfo struct to allow retrieving these cached values via new functions. Also use arch_initcall for the cpuinfo setup instead, as that now clearly is "architecture specific initialization" and also makes these information available slightly earlier.
