Register definition TRM unclear #546

Description

@marwaneltoukhy

There are some unclear register definitions in https://github.com/efabless/caravel/blob/main/docs/caravel_datasheet_2_register_TRM_r2.pdf

  1. mgmt GPIO registers have 32 bits, shouldn't it only be 1 bit?
  2. reg_mprj_io_xx definitions has some ambiguous bits
    • bit 2 | hold state value | Value of GPIO when in low-power state. @RTimothyEdwards mentioned that this should be removed
    • bit 5,6,7 | analog enable/select/polarity @RTimothyEdwards mentioned they should be removed as they're probably not functioning correctly because we do not have the vswitch enable bit set on the pads
  3. IRQ has 32 bit registers, shouldn't they be 1 bit? Registers also need to have better documentation
