MIPS changes for 4.15

Browse Source 
These are the main MIPS changes for 4.15.
 
 Fixes:
 - ralink: Fix MT7620 PCI build issues (4.5)
 - Disable cmpxchg64() and HAVE_VIRT_CPU_ACCOUNTING_GEN for 32-bit SMP
   (4.1)
 - Fix MIPS64 FP save/restore on 32-bit kernels (4.0)

 - ralink: Fix MT7628 pinmux (3.19)
 - BCM47XX: Fix LED inversion on WRT54GSv1 (3.17)
 - Fix n32 core dumping as o32 since regset support (3.13)
 - ralink: Drop obsolete USB_ARCH_HAS_HCD select
 
 Build system:
 - Default to "generic" (multiplatform) system type instead of IP22
 - Use generic little endian MIPS32 r2 configuration as default defconfig
   instead of ip22_defconfig
 
 FPU emulation:
 - Fix exception generation for certain R6 FPU instructions
 
 SMP:
 - Allow __cpu_number_map to be larger than NR_CPUS for sparse CPU id
   spaces
 
 Miscellaneous:
 - Add iomem resource for kernel bss section for kexec/kdump
 - Atomics: Nudge writes on bit unlock
 - DT files: Standardise "ok" -> "okay"
 
 Platform support:
 
  BMIPS:
  - Enable HARDIRQS_SW_RESEND
 
  Broadcom BCM63XX:
  - Add clkdev lookup support
  - Update clk driver, UART driver, DTs to handle named refclk from DTs
  - Split apart various clocks to more closely match hardware
  - Add ethernet clocks
 
  Cavium Octeon:
  - Remove usage of cvmx_wait() in favour of __delay()
 
  ImgTec Pistachio:
  - DT: Drop deprecated dwmmc num-slots property
 
  Ingenic JZ4780:
  - Add NFS root to Ci20 defconfig
  - Add watchdog to Ci20 DT & defconfig, and allow building of watchdog
    driver with this SoC
 
  Generic (multiplatform):
  - Migrate xilfpga (MIPSfpga) platform to the generic platform
 
  Lantiq xway:
  - Fix ASC0/ASC1 clocks
 
 Minor cleanups:
 - Define virt_to_pfn()
 - Make thread_saved_pc static
 - Simplify 32-bit sign extension in __read_64bit_c0_split()
 - DMA: Use vma_pages() helper
 - FPU emulation: Replace unsigned with unsigned int
 - MM: Removed unused lastpfn
 - Alchemy: Make clk_ops const
 - Lasat: Use setup_timer() helper
 - ralink: Use BIT() in MT7620 PCI driver
