Daniel P. Carvalho 2ef6153047 boards/mips/pic32mz: add Microchip EV49N51A board.
Add the Microchip EV49N51A Ethernet to Wi-Fi Bridge board, built around
the WFI32E01PE module (PIC32MZ-W1) with a LAN8720A Ethernet PHY.

The nsh configuration runs SYSCLK at 200 MHz with the console on UART1
(dedicated pins RA8/RA9, header J203, 115200 8N1) and drives the red and
green user LEDs on RK1/RK3.  It selects PGC2/PGD2 as the debug channel.
The SST26VF032B serial flash on SPI1 (dedicated pins, CS on RA1) is
exported as /dev/mtdblock0.  Its SPI frequency is set to 20 MHz: the SST26
driver's 64 MHz default is above PBCLK3/2 (25 MHz), which pic32mz_spi.c
does not handle.

mips-debug.ld is used with every toolchain.  It has no OUTPUT_FORMAT,
because XC32 and Pinguino name their little-endian ELF targets
differently; the board passes -EL to the linker instead.  With XC32 the
board builds with -mno-dsp -mno-dspr2: NuttX does not enable or save the
DSP ASE state.
