[PATCH printk v2 1/7] printk: Move buffer size defines

[John Ogness]

From: Thomas Gleixner <tglx@xxxxxxxxxxxxx>

Move the buffer size defines to console.h in preparation of adding a
buffer structure. The new buffer structure will be embedded within
struct console. Therefore console.h was chosen as the new home for
these defines.
