Add a new Kconfig LINUXPAYLOAD_CMDLINE_VPD_OVERWRITE that can overwrite Linux payload's kernel command line from VPD. Currently only overwrite Linux kernel command line 'loglevel' via VPD key 'kernel_log_level'. TESTED=On OCP Delta Lake, with kernel_log_level set to 0, warm reboot time can see about 10 seconds improvement comparing to kernel log level 7.
