drivers/ocp/vpd: Overwrite Linux payload's kernel command via VPD
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.
