Subject: [PATCH v4 3/3] printk: Remove redundant CONFIG_BASE_FULL

CONFIG_BASE_FULL is equivalent to !CONFIG_BASE_SMALL and is enabled by
default: CONFIG_BASE_SMALL is the special case to take care of.
So, remove CONFIG_BASE_FULL and move the config choice to
CONFIG_BASE_SMALL (which defaults to 'n')

Signed-off-by: Yoann Congal <yoann.congal@...le.fr>
---
v3->v4:
* Split "switch CONFIG_BASE_SMALL to bool" and "Remove the redundant
  config" (this patch) into two patches
* keep CONFIG_BASE_SMALL instead of CONFIG_BASE_FULL
