util: UartUpdateTool: support "--read-flash" flag
This patch creates a table to map the chip/device ID to the size of the
internal flash. When the "--read-flash" flag is given, uut will read
the device ID and chip ID registers and use them to look up the table to
get the flash size. Afterward, uut will read the flash content from
flash according to the size and write it to the file specified by the
"--file" flag.
