Merge tag 'ux500-dts-for-v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-nomadik into soc/dt

These are some Ux500 DTS updates for the v6.5 kernel cycle:
- Define the SRAM nodes that will be the preferred way to
  specify SRAM segments to drivers going forward.
- Fix up the naming of the STMPE nodes as we are merging
  proper YAML bindings which puts restrictions on those.
- Disable charging on the Ux500 HREF boards because these
  do not have any real batteries connected.

* tag 'ux500-dts-for-v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-nomadik:
  ARM: dts: ux500: Add eSRAM nodes
  ARM: dts: ux500: Fix STMPE device nodes
  ARM: dts: ux500: Disable charging on HREF boards
