Pull mtd updates from Miquel Raynal:
 "Core MTD changes:

   - We must ignore error -ENOENT from parsers on subpartitions which is
     a legitimate return value

   - PM support is added to the intel-dg driver

  Raw NAND changes:

   - The major change in this is the support for the Allwinner H616 NAND
     controller, which lead to numerous changes and cleanups in the
     driver.

   - Another notable change in this driver is the use of field_get() and
     field_prep(), but since the global support for this helpers is
     going to be merged in the same release as we start using these
     helpers, we undefine them in the first place to avoid warnings.

   - Marvell drivers layout handling changes have also landed, they fix
     previous definitions and abuses that have been made previously,
     which implied to relax the ECC parameters validation in the core a
     bit.

   - The Cadence NAND controller driver gets NV-DDR interface support.

  SPI NAND changes:

   - Support for FudanMicro FM25S01BI3 and ESMT F50L1G41LC is added.

  SPI NOR changes:

   - Fix SMPT parsing for S25FS-S flash family. They report variable
     dummy cycles for reads. This results in the default of 0 being
     used. This works for other Infineon chips, but not for the S25FS-S
     family. They need 8 dummy cycles. Add fixup hooks to specify that.
     Also add fixup hooks to fix incorrect map ID data in SFDP.

   - Add support for a bunch of Winbond flashes. Their block protection
     information is not discoverable, so they need to have an entry in
     the flash tables to describe that.

   - Some cleanups for Micron flash support.

   - Add support for Micron mt35xu01gbba.

   - Some SPI controllers like the Intel one on the PCI bus do not
     support the read CR opcode (0x35). Do not use the opcode if the
     controller does not support it.

  Aside from these main changes, there is the usual load of API updates,
  kdoc fixes, potential memory leaks fixes, etc"
