amd/pi/hudson: Move APIC enable to CPU file
Relocate the enabling of the LAPIC out of the southbridge source and
surround it with a check for CONFIG_UDELAY_LAPIC (typical for AMD
systems). The LAPIC is now enabled for all cores; not only the BSP,
and not only when the UART is used.
This solves the problem of APs not having their APICs enabled when
the timer is expected to be functional, e.g. verstage often uses
do_printk_va_list() instead of do_printk() which exits early for
APs when CONFIG_SQUELCH_EARLY_SMP=y.
The changes were tested with two Gardenia builds, one using verstage
and another with CONFIG_SQUELCH_EARLY_SMP=n.
