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.

f81a673ec4 altera_qspi: skip erase if the sector is blank

a1b1d7eceb altera_qspi: set fail_addr for erase ops
If the erase fails, fail_addr might indicate exactly which block
failed. If fail_addr = MTD_FAIL_ADDR_UNKNOWN, the failure was not
at the device level or was not specific to any particular block.

9e957aa4ce altera_qspi: call callback even if the erase failed
Erase is an asynchronous operation.  Device drivers are supposed
to call instr->callback() whenever the operation completes, even
if it completes with a failure.

f118fe5cf9 altera_qspi: fix erase and write error code
Fix erase and write error code, which should be "protected".

From the "Embedded Peripherals IP User Guide" of Altera,

The "Illegal write" flag indicates that a write instruction is
targeting a protected sector on the flash memory. This bit is
set to indicate that the IP has cancelled a write instruction.

The "Illegal erase" flag indicates that an erase instruction has
been set to a protected sector on the flash memory. This bit is
set to indicate that the IP has cancelled the erase instruction.

38a0f36e83 mtd: add altera quadspi driver
Add Altera Generic Quad SPI Controller support. The controller
converts SPI NOR flash to parallel flash interface. So it is
not like other SPI flash, but rather like CFI flash.
