Sometimes the ADC controller met some problems, and it will not complete
the data conversion, that will can not wake up the read process any more
to block users. So we should add one maximum conversion time to avoid
this issue.

PNI RM3100 is a high resolution, large signal immunity magnetometer,
composed of 3 single sensors and a processing chip with a MagI2C
interface.
Following functions are available:
- Single-shot measurement from
/sys/bus/iio/devices/iio:deviceX/in_magn_{axis}_raw
- Triggerd buffer measurement.
- DRDY pin for data ready trigger.
- Both i2c and spi interface are supported.
- Both interrupt and polling measurement is supported, depends on if
the 'interrupts' in DT is declared.

'pcie_link_status' is a global variable which is being used as a
mask to know which virtual bridges are or not enabled. Instead of
this extract a new 'mt7621_pcie_init_virtual_bridges' function where
a similar local variable is used for the same task. This allow us to
properly configure the virtual PCI-PCI bridges in configuration
registers of the mt7621 pci controller. For a correct initiation of
which is connected use 'enabled' field of 'mt7621_pcie_port' struct.
With this change driver probe function gets a bit cleaner and readable.

Driver probe function check for a bit in 'pcie_link_status' for
enabling the pcie port or not. Instead of this add 'enabled' field
in 'mt7621_pcie_port' structure and check its value to achieve this
inside a new 'mt7621_pcie_enable_ports' function. The offsets for
the correct port are derived from the slot of the port. This field
'enabled' is properly initilized in 'mt7621_pcie_init_port'. Also
depending of the number of ports enabled we have to properly init
its registers taking into account that we will use virtual bridges
from zero to num_slots_enabled as follows:
- Only one enabled -> only enable virtual bridge 0.
- Two enabled -> enable virtual bridges 0 and 1.
- Three enabled -> enable virtual bridges 0, 1 and 2.
