Add stub code for SDIO support, capable of verifying card responds to CMD5.
This commit also changes the architecture of the SDIO probe step to make
adding new protocol support more streamlined, and enable compiling out
support for undesired protocols.

The HSI48 is enabled by clock control driver.
It is no more done by each driver that requires this clock
However when using rng or sdmmc or bluetooth/ipm or usb,
the HSI48 clock must be present in the DTS.
Add a warning for this particular check but keep the deprecated
HSI48 clock enable : keeping for legacy but to remove later.

Fail with error if any of flashdisk partition assumptions are not met:
* uniform page size through the whole partition
* flashdisk starts at page boundary
* flashdisk ends at page boundary
Read-only flashdisks are not subject to above conditions because the
cache buffer is not used for read-only flashdisks.
The checks can be disabled via Kconfig option to save code space.

Force cache-size to 0 and treat flashdisk as read-only when backing
partition has read-only flag set. This allows users to save RAM when the
application does not write to the flashdisk, e.g. when a predefined FAT
filesystem is used.

Cache written data to avoid rewriting same flash page multiple times
when writing subsequent flash pages. The cache is used for reads to
account for reading not yet committed (i.e. dirty) page data. Speeding
up reads is not intention of this patch and therefore the read path
does not modify cache state.

The "spi-max-frequency" property already exists, but was unused. This
now sets the SPI clock frequency to this value (limited to 24MHz) once
initialisation is complete.
Due to the nature of the SPI API, it is necessary to have two separate
configuration structures to switch clock speed as some SPI drivers only
compare pointers to detect changes.
