6de5a862cd drivers/input: Add driver for Goodix GT9XX Touch Panel 
This PR adds the driver for Goodix GT9XX I2C Touch Panel, which will be called by PINE64 PinePhone.

Our driver follows the design of the NuttX Driver for [Cypress MBR3108](https://github.com/apache/nuttx/blob/master/drivers/input/cypress_mbr3108.c).

We have documented our driver here: ["NuttX Touch Panel Driver for PinePhone"](https://lupyuen.github.io/articles/touch2#appendix-nuttx-touch-panel-driver-for-pinephone)

`drivers/input/Kconfig`: Added option `INPUT_GT9XX` to select GT9XX Driver

`drivers/input/Make.defs`: Added GT9XX Driver to Makefile

`drivers/input/gt9xx.c`, `gt9xx.h`: I2C Driver for GT9XX Touch Panel

34d2cde8a8 net/l2/l3/l4: add support of iob offload 
1. Add new config CONFIG_NET_LL_GUARDSIZE to isolation of l2 stack,
   which will benefit l3(IP) layer for multi-MAC(l2) implementation,
   especially in some NICs such as celluler net driver.

new configuration options: CONFIG_NET_LL_GUARDSIZE

CONFIG_NET_LL_GUARDSIZE will reserved l2 buffer header size of
network buffer to isolate the L2/L3 (MAC/IP) data on network layer,
which will be beneficial to L3 network layer protocol transparent
transmission and forwarding

------------------------------------------------------------
Layout of frist iob entry:

        iob_data (aligned by CONFIG_IOB_ALIGNMENT)
            |
            |                  io_offset(CONFIG_NET_LL_GUARDSIZE)
            |                                |
            -------------------------------------------------
      iob   |            Reserved            |    io_len    |
            -------------------------------------------------

-------------------------------------------------------------
Layout of different NICs implementation:

        iob_data (aligned by CONFIG_IOB_ALIGNMENT)
            |
            |                 io_offset(CONFIG_NET_LL_GUARDSIZE)
            |                                |
            -------------------------------------------------

            ---------------------------------|---------------
 ipforward  |            Reserved            |    io_len    |
            -------------------------------------------------

--------------------------------------------------------------------

2. Support iob offload to l2 driver to avoid unnecessary memory copy

Support send/receive iob vectors directly between the NICs and l3/l4
stack to avoid unnecessary memory copies, especially on hardware that
supports Scatter/gather, which can greatly improve performance.

new interface to support iob offload:

  ------------------------------------------
  |    IOB version     |     original      |
  |----------------------------------------|
  |  devif_iob_poll()  |   devif_poll()    |
  |       ...          |       ...         |
