At least the internal pull-up is not working for GPIO32 and GPIO33 when it is configured by setting FUN_WPU in IO_MUX_x_REG.
As a workaround, setting bits 27 and 22 in register 0x3FF4848C (RTCIO_XTAL_32K_PAD_REG) works at least.
However a general solution must be implemented.
- check other GPIOs as well.
- check whether pull-down works.
