Introduce device tree support for the Interface Plus [IFP] Mezzanine
peripheral expansion card used with the Qualcomm Lemans Evaluation Kit
(EVK).

The Lemans IFP Mezzanine is an additional add-on card which can be
stacked on top of Lemans-evk board to extend peripheral capabilities of
lemans-evk used for industrial applications.

It connects via expansion headers on the lemans-evk and provides
following peripherals :
- 4x Type A USB ports in host mode.
- TC9563 PCIe switch, which has following three downstream ports (DSP) :
   - 1st DSP routes to M.2 E-key connector, intended for WLAN modules.
   - 2nd DSP routes to M.2 B-key connector, intended for cellular
     modems.
   - 3rd DSP with support for Dual Ethernet ports.
- eMMC.
- Additional 2.5GbE Ethernet PHY connected to native EMAC with support
  for MAC Address configuration via NVMEM.
- EEPROM.
- LVDS Display.

Changelog

v4:
  - Rename file to lemans-evk-ifp-mezzanine to align with that of
    mezzanine naming convention.
  - Add fixed-regulators to satisfy what is required by the bindings
    instead of representing the complete tree which is present on the
    board.
  - Update commit text to communicate USB-Hub, LVDS display and mini DP
    support will be added later once the dependent changes are
    available.
  - Remove "power-source", "input-disable" and "output-enable"
    properties
    from tc9563_resx_n node and add "output-high" property instead to
    align with TLMM supported bindings.
  - v3-link: [3]

v3:

  - v2-link: [2]

v2:
   - Move "regulator-always-on" and "regulator-boot-on" nodes at the end
