MIPS changes for 4.17

These are the main MIPS changes for 4.17. Rough overview:
 
  (1) generic platform: Add support for Microsemi Ocelot SoCs
 
  (2) crypto: Add CRC32 and CRC32C HW acceleration module
 
  (3) Various cleanups and misc improvements
 
 Miscellaneous:
 
  - Hang more efficiently on halt/powerdown/restart
 
  - pm-cps: Block system suspend when a JTAG probe is present
 
  - Expand make help text for generic defconfigs
    - Refactor handling of legacy defconfigs
 
  - Determine the entry point from the ELF file header to fix microMIPS
    for certain toolchains
 
  - Introduce isa-rev.h for MIPS_ISA_REV and use to simplify other code
 
 Minor cleanups:
 
  - DTS: boston/ci20: Unit name cleanups and correction
 
  - kdump: Make the default for PHYSICAL_START always 64-bit
 
  - Constify gpio_led in Alchemy, AR7, and TXX9
 
  - Silence a couple of W=1 warnings
 
  - Remove duplicate includes
 
 Platform support:
 
 ath79:
 
  - Fix AR724X_PLL_REG_PCIE_CONFIG offset

  - FIRMWARE: Use mac_pton() for MAC address parsing

* Microsemi MIPS CPUs
Boards with a SoC of the Microsemi MIPS family shall have the following
properties:
Required properties:
- compatible: "mscc,ocelot"
* Other peripherals:
o CPU chip regs:
The SoC has a few registers (DEVCPU_GCB:CHIP_REGS) handling miscellaneous
functionalities: chip ID, general purpose register for software use, reset
controller, hardware status and configuration, efuses.
Required properties:
- compatible: Should be "mscc,ocelot-chip-regs", "simple-mfd", "syscon"
- reg : Should contain registers location and length
Example:
syscon@71070000 {
compatible = "mscc,ocelot-chip-regs", "simple-mfd", "syscon";
reg = <0x71070000 0x1c>;
};
o CPU system control:
The SoC has a few registers (ICPU_CFG:CPU_SYSTEM_CTRL) handling configuration of
the CPU: 8 general purpose registers, reset control, CPU en/disabling, CPU
endianness, CPU bus control, CPU status.
Required properties:
- compatible: Should be "mscc,ocelot-cpu-syscon", "syscon"
- reg : Should contain registers location and length
Example:
syscon@70000000 {
compatible = "mscc,ocelot-cpu-syscon", "syscon";
reg = <0x70000000 0x2c>;
};
