da3fe24759 x86: Rename pcat_ to i8254 and i8259 accordingly
Rename pcat_timer.c to i8254.c and pcat_interrupts.c to i8259.c,
to match their header file names (i8254.h and i8259.h).

6c5052716e x86: Rename CONFIG_SYS_NUM_IRQS to SYS_NUM_IRQS
CONFIG_SYS_NUM_IRQS is actually not something we can configure,
but an architecture defined number of ISA IRQs. Move it from
x86-common.h to asm/interrupt.h and rename it to SYS_NUM_IRQS.

1dae2e0eb6 x86: Refactor interrupt_init()
Rename interrupt_init() in arch/x86/lib/pcat_interrupts.c to
i8259_init() and create a new interrupt_init() in
arch/x86/cpu/interrupt.c to call i8259_init() followed by a
call to cpu_init_interrupts().

4372a9eca5 x86: Call cpu_init_interrupts() from interrupt_init()
Currently cpu_init_interrupts() is called from cpu_init_r() to
setup the interrupt and exception of the cpu core, but at that
time the i8259 has not been initialized to mask all the irqs
and remap the master i8259 interrupt vector base, so the whole
system is at risk of being interrupted, and if interrupted,
wrong interrupt/exception message is shown.

fa82f871c8 Convert ISO-8859 files to UTF-8
There was a mix of UTF-8 and ISO-8859 files in the U-Boot source
tree, which could cause issues with the patchwork review system.
This commit converts all ISO-8859 files to UTF-8.
