This member is used by the cpufreq notifier callback to get the updated clock rate. Also adds a member 'cpufreq_flag' to the plat_serial8250_port and uart_port structures which decides the requirement of cpufreq registration for each individual ports. If the port requires registration then 'cpufreq_flag'
