The code to poke the system integration module to disable clock gating
for UARTs only works for UART0-3 since all the bits are in the same
register. However, clocks for UART4 and UART5 are controlled by
another register. This means that we have been writing to the wrong
bit for enabling UART4.
This patch fixes this issue, and moves the clock gating clock into
board initialization. The incorrect code has also been removed to
prevent accidental mis-use. The dev_data struct is no longer needed
for uart_k20, so that is removed as well.

ANSI sequences may have a numbered prefix which means that the action
needs to be taken the number amount of times, e.g. "Esc[ValueA" (move
cursor forward Value number of characters). Some ANSI commands also
have two preceding values, such as Esc[Line;ColumnH (move cursor to
Line & Column).
To support these ANSI sequences we need to track a bit of extra state,
most conveniently done using a bit field. Since the ANSI parsing logic
gets a bit long at this point it's refactored into its own handle_ansi()
function.

Instead of keeping track how many characters we need to move back to
get to the original position, take advantage of the save/restore
escape sequences. This allows us to drop the extra 'i' variable from
both insert_char() as well as del_char().

MVIC has only one local interrupt: the timer IRQ. What IRQ line
to use is not fixed, instead it is programmed into the LVTTIMER
register. This is unlike LOAPIC which has a fixed IRQ for the timer
and instead the *vector* to use for it is programmed into LVTTIMER.
We don't want _loapic_int_vec_set() to do anything as the relationship
between IRQ lines and vectors is fixed and we do not want to be
programming vector numbers into bits 0-3 of LVTTIMER.
The IRQ line to use for timer interrupts is programmed into LVTTIMER
when the MVIC is initialized.

Quark SE Lakemont core has a hardware bug where the LOAPIC does
not properly notify the IOAPIC to clear the IRR bit for level-
triggered interrupts.
This patch introduces a workaround where the vector ID of the
in-service interrupt is manually written to the IOAPIC_EOI
register, resulting in the bit being cleared.
Unfortunately, in the context where EOI happens it's very difficult
to identify which IRQ line is being serviced, so this is done
unconditionally for all interrupts vectors whether they are registered
in the IOAPIC RTE table or not.

A special situation may occur when a processor raises its task
priority to be greater than or equal to the level of the
interrupt for which the processor INTR signal is currently
being asserted. If at the time the INTA cycle is issued, the
interrupt that was to be dispensed has become masked (programmed
by software), the local APIC will deliver a spurious-interrupt
vector. Dispensing the spurious-interrupt vector does not affect
the ISR, so the handler for this vector should return without an EOI.

By default, since we don't have special support for control characters
we should simply ignore them. This includes both pure (single) control
characters as well as ANSI escape sequences. The most important
control character to support for basic editing is Backspace.
The terminal creates a Delete (DEL) character by default when
Backspace is pressed. It also treats the Backspace character ('\b') as
a non-destructive backspace. To create the effect of destructive
backspace we have to send the sequence "\b \b".
