e160f7d430 dm: core: Replace of_offset with accessor
At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to
access this field through an inline function.

6d0e34bf4e mmc: sdhci: Distinguish between base clock and maximum peripheral frequency
The sdhci controller assumes that the base clock frequency is fully supported by
the peripheral and doesn't support hardware limitations. The Linux kernel
distinguishes between base clock (max_clk) of the host controller and maximum
frequency (f_max) of the card interface. Use the same differentiation and allow
the platform to constrain the peripheral interface.

6f88a3a5d9 mmc: sdhci: remove the SDHCI_QUIRK_NO_CD
This quirk doesn't need anymore.
It's replaced to get_cd callback function.

5e96217f04 mmc: pic32_sdhci: move the code to pic32_sdhci.c
This code is used for only pic32_sdhci controller.
To remove the "#ifdef", moves to pic32_sdhci.c.
And use the get_cd callback function.

1221ce459d treewide: replace #include <asm/errno.h> with <linux/errno.h>
Now, arch/${ARCH}/include/asm/errno.h and include/linux/errno.h have
the same content.  (both just wrap <asm-generic/errno.h>)

Replace all include directives for <asm/errno.h> with <linux/errno.h>.
