This adds basic support for width modifier when printing integers.
Supported specifiers are u,i,d,x,X. Width '*' is not supported.
Flag '0' for left-pading number with zero is also supported.
examples:
printk("0x%x 0x%02x 0x%04x 0x%08x\n", 1, 1, 1, 1);
0x1 0x01 0x0001 0x00000001
printk("0x%x 0x%2x 0x%4x 0x%8x\n", 1, 1, 1, 1);
0x1 0x 1 0x 1 0x 1
This should make printk usable for pretty printing u8 and u16 integers.

This is to support a printf test case where we need to know
the existing value so we can chain it.

We now allow modifier codes h, l, and z, although at the
moment they are simply dropped. This is to allow us to warn on
incorrect printk() usage by the compiler. These arguments get
promoted to int when they are passed as arguments so this
may never need to be addressed, although there may be implications
for (future) support for systems with 16-bit integers.
We still don't print 64-bit integers properly. but this is
nothing new.

It was never being used due to the obj-$(CONFIG_PRINTK) in the
Makefile, and the new method using a static inline function in
the printk.h header performs better since there won't be
function call overhead.
