Reword frequency and timing selection logic for SDIO framework so that
the maximum supported timing mode between the card and host will be
selected, even if the maximum frequency supported by the host is not
equal to the maximum frequency for that mode.
Also, resolve an issue where a host and card combo only supporting HS
mode or worse would still use legacy timing mode, because the CCCR flags
were not being checked when checking if HS bus speed could be used.

Previously, if an SD I/O operation was attempted while another thread
held the mutex for the SD card, the I/O operation would simply fail. Add
a timeout to k_mutex_lock calls within the SD subsystem, so that
multithreaded access to the SD card instead blocks until the SD card is
available for I/O

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.
