agesawrapper: Fix endless loop on bettong

AGESA AmdInitEarly() reconfigures the lapic timer in a way that
conflicts with lapic/apic_timer.

This results in an endless loop when printk() is called after
AmdInitEarly() and before the apic_timer is initialized.

This patch forces a reconfiguration of the timer after
AmdInitEarly() is called.

Codepath of the endless loop:

printk()->
  (...)->
    uart_tx_byte->
      uart8250_mem_tx_byte->
        udelay()->
          start = lapic_read(LAPIC_TMCCT);
	  	do {
			value = lapic_read(LAPIC_TMCCT);
		} while ((start - value) < ticks);
         [lapic_read returns the same value after AmdInitEarly()]
