V5 depend on below patches. 
 - https://lore.kernel.org/patchwork/patch/1237642/ [Add helpers
   for enabling/disabling a path]
 - https://patchwork.kernel.org/patch/11491027/ [Add devm_of_icc_get()
   as exported API for users ]

dt-binding patch for QUP drivers.
 - https://patchwork.kernel.org/patch/11534149/ [Convert QUP bindings
        to YAML and add ICC, pin swap doc]

High level design:
 - QUP wrapper/common driver.
   Vote for QUP core on behalf of earlycon from probe.
   Remove BW vote during earlycon exit call

 - SERIAL driver.
   Vote only for CPU/CORE path because driver is in FIFO mode only
   Vote/unvote from qcom_geni_serial_pm func.
   Bump up the CPU vote from set_termios call based on real time need

 - I2C driver.
   Vote for CORE/CPU/DDR path
   Vote/unvote from runtime resume/suspend callback
   As bus speed for I2C is fixed from probe itself no need for bump up.

 - SPI QUP driver.
   Vote only for CPU/CORE path because driver is in FIFO mode only
   Vote/unvote from runtime resume/suspend callback
   Bump up CPU vote based on real time need per transfer.

 - QSPI driver.
   Vote only for CPU path
   Vote/unvote from runtime resume/suspend callback
   Bump up CPU vote based on real time need per transfer.

Changes in V2:
 - Add devm_of_icc_get() API interconnect core.
 - Add ICC support to common driver to fix earlyconsole crash.

Changes in V3:
 - Define common ICC APIs in geni-se driver and use it across geni based
   I2C,SPI and UART driver.

Changes in V4:
 - Add a patch to ICC core to scale peak requirement
   as twice of average if it is not mentioned explicilty.

Changes in V5:
 - As per Georgi's suggestion removed patch from ICC core for assuming
   peak_bw as twice of average when it's not mentioned, instead assume it
   equall to avg_bw and keep this assumption in ICC client itself.
 - As per Matthias suggestion use enum for GENI QUP ICC paths.
