Added board support for holybro_durandal-v1

Durandal:Fix PLL settings

durandal-v1:Move I2C123, I2C4 to HSI.

   Not liking using HSI but, F7 has, and in reality there is no
  requerment for accuracy.

durandal-v1:board config set 400kHz on card probe

durandal-v1:Board SDMMC Clock Not greater then 25 mHz

durandal-v1:Fix PLL3 configuration typo and value

CI build config for holybro_durandal-v1

durandal-v1:Kconfig - add knob to ensure ARCH_MATH_H is kept

   Upstream changes added ARCH_HAVE_MATH_H to protect from archs
   without math.h from causing isses for users setting
   CONFIG_ARCH_MATH_H and getting errors. PX4 provides a math.h
   and we need CONFIG_ARCH_MATH_H set. So this Selects
   ARCH_HAVE_MATH_H perserving CONFIG_ARCH_MATH_H a defconfig

Track master LED removal

durandal-v1: bmi055 -> bmi088

bmi088 is what the board uses

durandal-v1:add PX4IO support

durandal-v1 rc.board_sensors: start baro

durandal-v1: remove segway module

durandal:Run at 480 Mhz

durandal-v1: build thermal control module

durandal-v1: enable IMU thermal control by default

durandal-v1:Track upstream adc start moved to rc.board_sensors

durandal-v1:Track upstream mavlink start moved to rc.board_mavlink
