Per ST doc DM00035129.pdf "DocID022063 Rev 5", the STM32F415xx data sheet,
table 40 on page 110 of the PDF, 32-bit program operation is only possible
above 2.7 Volts.
In order to support programming on devices running at lower voltages, this
commit adds an 8-bit programming mode and the necessary tests to enable it
when the reported voltage is below 2.7 Volts.
The indentation of various st-link source files is highly inconsistent.
Reindent all source files to 4 space indentions for consistency.
I went with 4 space indentations, as it was the most common style.
