The flags in struct console_device have to be initialized
to zero. Otherwise the following can happen:
- console_register sets the initial baudrate of a new console
before we set the global console init state to CONSOLE_INIT_FULL.
- In console_baudrate_set we test whether the current console is
active which may be true because of unitialized flags.
- we then call getc() to wait for the user to accept the new settings
and we are stuck because of the CONSOLE_UNINITIALIZED state
we will never get anything from getc().
Looking back this explains some cases for me when barebox refused
to start and I really wonder why this did not become a more visible
problem before.

The NAND_READ_OOB Kconfig option is used to
a) creating a cdev for reading OOB data
b) compiling in mtd->read_oob support
The former was intended and that's also what the Kconfig help
says. The latter though was implicit and wrong. mtd->read_oob
is also used by the bbt code which resulted in a NULL pointer
deref when compiled with BBT but without NAND_READ_OOB.
To fix this, split the option into two. The now invisible
option NAND_OOB_DEVICE is only responsible for b) and gets
selected when necessary.

The device resources are much smaller, the resource mechanism
revealed this because of overlapping devices.

Newer pcm038 are populated with a PC28F256P30BFE NOR-Flash.
This flash requires different CS values.
The values also work with older NOR-Flashes.

uncompress_buf is used each time uncompress is called, so
make sure it is initialized correctly so that we do not
call free() on an already free pointer.

Since fprintf and console_puts now return the number of
character written the prototypes have changes. We forgot
to fix console_simple which now fails to compile with:
common/console_simple.c:48:6: error: conflicting types for 'fprintf'
include/stdio.h:57:5: note: previous declaration of 'fprintf' was here
common/console_simple.c:67:6: error: conflicting types for 'console_puts'
include/stdio.h:20:5: note: previous declaration of 'console_puts' was here
Fix this by returning the proper numbers of characters written.
