Instead of only allowing complete devices we now also allow single
partitions to look for bootloader spec entries.
Normally the bootloader spec defines a way to find a partition containing /boot
on a device. On embedded systems it's often useful instead to have only a
single partition image which contains both the kernel and the root filesystems.
This partition image may be written to the device multiple times. With this
patch they can be booted with 'boot emmc0.<partno>'

There is no much sense in having the pinctrl drivers be user selectable
as all arches using on of them already selects the right one.
So to avoid presenting the user with the choice to enable unrelated
pinctrl drivers or pushing lots of dependencies into the Kconfig just
drop the configurability.

There are some reasons for using YAMON-style memory map:
* we can run Linux kernel from barebox;
* we can use GXemul for running barebox.

Drivers currently cannot implement explicit cache handling and rely on
running the same code before and after mmu_initcall() without crashing.
Depending on the chosen config options, the cache functions are not yet
setup and using them early on ends in a null pointer dereference.
The RPi's mailbox driver is such a case; it requires cache handling once
the MMU is fully set up and yet the RPi setup needs to use the driver to
get the memory size before mem_initcall() and hence mmu_initcall().
Fix this by checking the cache_fns pointer before dereferencing it.
