HAL_AVR: set initial bus speed on MPU6k to 500kHz, then change to 8MHz
...
this should allow us to work even with older chips. See the MPU6000
product specification, which says max 20MHz for sensor and interrupt
regs, and max 1MHz for all other regs

HAL_AVR: added specialised transfer functions for MPU6k and APM1 ADC
...
this saves quite a lot of time in interrupts

HAL_AVR: corrected includes to replace #include "$HEADER" with #inlcude "utility/$HEADER"
...
adding -I for EVERY DIRECTORY isn't desirable

HAL_AVR: added bulk transfer() method
...
this is quite a lot faster than the byte at a time method

AP_HAL: rename Sempahore.h to Semaphores.h
...
this is needed to allow build on MacOS, as its case-insensitive
filesystem picks up the NuttX semaphore.h
