Make it clear that the name of the constant being defined is a string.
When the value being defined is also a string, use a new
DECL_CONSTANT_STR() macro.

Default to running dfu-util via sudo as most machines will not have
the user setup with permissions to access the raw usb device.

Commit e18501d0 broke the build for targets that added objects to
klipper.elf via adding dependencies. Rework the build so that it is
possible to add objects to klipper.elf via a new OBJS_klipper.elf
makefile variable.

Move the definition of SERIAL_BAUD to the main src/Kconfig file. Only
show this as an option if the user selects the ability to configure
low-level options.

The lpc176x ADC is extremely noisy. Implement a 5 order median filter
on each ADC read to weed out obviously incorrect readings.

The sam3 i2c code and the linux code use a 7-bit i2c address, while
the avr, lpc176x, and samd21 i2c code uses an 8-bit address with the
least significant bit always zero. A similar issue occurred in the
host code (sx1509.py and replicape.py use 7-bit addresses while
uc1701.py and mcp4451.py use 8-bit addresses).
Consistently use 7-bit addresses in all the code. This breaks
compatibility between host and mcu software, so make a change to the
config_i2c command to force users to synchronize software updates.
This also breaks common Smoothieboard configs, so update the mcp4451
code to validate the i2c_address.

Pass the gpio id instead of the bank/pin to gpio_peripheral(). This
is in keeping with other ARM ports.

Scale the bus speed within the peripheral instead of on the system bus
as scaling on the system bus slows down general register access to the
peripheral.

Scaling the timer on the system bus has a notable impact on
performance. So, scale the timer within the timer hardware itself.

Use new usb_read_ep0_setup() function when reading a setup packet -
this allows the low-level usb hardware code to better handle errors.

Use "ep0" when referring to endpoint0 - don't use "setup" as that can
be confused with the low-level usb setup token.

It's common for boards to have restrictions on the type of each
endpoint. So, make it possible for the board to select the endpoint
ids for each endpoint.

No need to include separate cmsis files from the mbed project - the
standard CMSIS_5 files work fine.
