sd: Add common SD initialization code All SD cards require SD CMD0 (reset) and CMD8 (send IF cond) at boot. Add this portion of the initialization flow to SD subsystem, as well as query command to check if card is SDIO. Signed-off-by: Daniel DeGrasse <daniel.degrasse@nxp.com>

sd: Changed Init Header Structure In sd subsystem, made one header for all the init functions instead of having a bunch of header files with one function. Signed-off-by: Declan Snyder <declan.snyder@nxp.com>

includes: prefer <zephyr/kernel.h> over <zephyr/zephyr.h> As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>. This patch proposes to then include <zephyr/kernel.h> instead of <zephyr/zephyr.h> since it is more clear that you are including the Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a catch-all header that may be confusing. Most applications need to include a bunch of other things to compile, e.g. driver headers or subsystem headers like BT, logging, etc. The idea of a catch-all header in Zephyr is probably not feasible anyway. Reason is that Zephyr is not a library, like it could be for example `libpython`. Zephyr provides many utilities nowadays: a kernel, drivers, subsystems, etc and things will likely grow. A catch-all header would be massive, difficult to keep up-to-date. It is also likely that an application will only build a small subset. Note that subsystem-level headers may use a catch-all approach to make things easier, though. NOTE: This patch is **NOT** removing the header, just removing its usage in-tree. I'd advocate for its deprecation (add a #warning on it), but I understand many people will have concerns. Signed-off-by: Gerard Marull-Paretas <gerard.marull@nordicsemi.no>

sd: Changes framework to support MMC - Adds mmc.c - Edits sd.c to init and probe MMC - Adds mmc init to sd_init - Some functions from sdmmc.c should be in sd_ops because they can be used by both sdmmc and mmc. Signed-off-by: Declan Snyder <declan.snyder@nxp.com>
