To apply the workaround:

if ((NRF_FICR->INFO.VARIANT & 0x0000FF00u) < (((uint32_t) 'E') << 8))
{
    *((volatile uint32_t*) 0x40001774u) = (*((volatile uint32_t*) 0x40001774u) & 0xFFFFFFFEu) | 0x01000000u;
}

To reverse the workaround:

if ((NRF_FICR->INFO.VARIANT & 0x0000FF00u) < (((uint32_t) 'E') << 8))
{
    *((volatile uint32_t*) 0x40001774u) = (*((volatile uint32_t*) 0x40001774u) & 0xFEFFFFFFu) | 0x00000001u;
}

The fix required for PAN182 will only be applied to Rev 2 silicon and only needs to be done every time the radio power is enabled.

if ((*((uint32_t*) 0x10000130ul) == 0x6ul) && (*((uint32_t*) 0x10000134ul) == 0x6ul))
{
    *(volatile uint32_t *) 0x4000173C |= (1u << 10);
}
