list_options() broken in ccs9

[webbcam]

Using the list_options() function raises an Exception when using CCSv9.

Context

When using the list_options() function (tiflash options-list on CLI) raises an KeyError Exception for 'beginsWith'. This is due to a change in the device xml files. The flash_properties.py helper needs to be updated to handle this.

This is due to a change in the FlashPropertiesTranslator.xml files in CCS 9 which added FlashProperties that use a 'regex' keyword instead of 'beginsWith'. TIFlash seems to be using the entries which use 'regex' instead of 'beginsWith'.

Process

To reproduce:
CLI: tiflash -d CC1310F128 options-list
Python: tiflash.list_options(devicetype="CC1310F128")

Expected result

Should list flash options for device.

Possible Fix

TIFlash should handle the retrieve the used keyword rather than using a hardcoded one e.g. 'beginsWith'
