board_f: x86: Use checkcpu() for CPU init

At present we misuse print_cpuinfo() do so CPU init on x86. This is done
because it is the next available call after the console is enabled. But
several arches use checkcpu() instead. Despite the horrible name (which
we can fix), it seems a better choice.

Adjust the various x86 CPU implementations to move their init code into
checkcpu() and use print_cpuinfo() only for printing CPU info.

x86: Force 32-bit jumps in interrupt handlers

Depending upon the compiler used, IRQ entries could vary in sizes. With
GCC 5.x, the code generator will use short jumps for some IRQ entries
but near jumps for others. For example, GCC 5.4.0 generates the
following:

$ objdump -d interrupt.o
<snip>
00000207 <irq_18>:
207: 6a 12 push $0x12
209: eb 85 jmp 190 <irq_common_entry>

0000020b <irq_19>:
20b: 6a 13 push $0x13
20d: eb 81 jmp 190 <irq_common_entry>

0000020f <irq_20>:
20f: 6a 14 push $0x14
211: e9 7a ff ff ff jmp 190 <irq_common_entry>

00000216 <irq_21>:
216: 6a 15 push $0x15
218: e9 73 ff ff ff jmp 190 <irq_common_entry>

This causes a problem in cpu_init_interrupts(), because the IDT setup
assumed same sizes for all IRQ entries. GCC 4.x always generated 32-bit
jumps, so this previously was not a problem.

The fix is to force 32-bit near jumps for all entries within the
inline assembly. This works for GCC 5.x, and 4.x was already using
that form of jumping.
