A clk structure member has been added to the platform and port data structures. 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.

Added a boolean member "enable_cpufreq" to the uart_port and serial8250_port structures. This indicates the requirement of cpu freq registration for each individual ports. > 3.
