Compile error from generated device module file

[demotomohiro]

I tried svd2nim for SVD file for RP2040 in https://github.com/raspberrypi/pico-sdk/blob/master/src/rp2040/hardware_regs/RP2040.svd
It generated RP2040.nim with following code:

type ROSC_CTRL_FREQ_RANGE* {.size: 4.} = enum
  LOW = 0xfa4,
  MEDIUM = 0xfa5,
  HIGH = 0xfa7,
  TOOHIGH = 0xfa6,

It causes compile error: Error: invalid order in enum 'TOOHIGH'.

It seems above code was generated from following code:

                            HIGH uses stages 4 to 7 
                            TOOHIGH uses stages 6 to 7 and should not be used because its frequency exceeds design specifications

                            The clock output will glitch when changing the range down 
                            Note: the values here are gray coded which is why HIGH comes before TOOHIGH</description>

TOOHIGH has value lower value than HIGH.
svd2nim need to sort enumerated Value when generating code.
