Add CONFIG_SYS_FSL_QSPI_AHB in header file to enable AHB in driver.
In order to count the time, add CONFIG_CMD_TIME.
Using AHB read can improve the the read speed about 30%.
AHB read:
=> time sf read 0x8f800000 0 100000
SF: 1048576 bytes @ 0x0 Read: OK
time: 0.174 seconds
=> time sf read 0x8f800000 1000000 100000
SF: 1048576 bytes @ 0x1000000 Read: OK
time: 0.174 seconds
IP read:
=> time sf read 0x8f800000 0 100000
SF: 1048576 bytes @ 0x0 Read: OK
time: 0.227 seconds
=> time sf read 0x8f800000 1000000 100000
SF: 1048576 bytes @ 0x1000000 Read: OK
time: 0.227 seconds
Note:
Quad read is not supported in driver, now. In my side, using AHB and Quad read
can achieve about 16MB/s. Anyway, I have plan to reimplement the driver using
DTB and DM, then make the code cleaner and more feature can be added.

mx6sxsabresd revb board uses 32MB qspi flash, reva board uses 16MB qspi
flash. Currently, the default supported platform is revb board.
If want to configure for reva board, just define CONFIG_MX6SX_SABRESD_REVA
in mx6sxsabresd.h to support reva qspi flashes whose size is 16MB.

Configure the pad setting and enable qspi clock to support qspi
flashes access.
Add QSPI related macro in configuration header file.
Note:
mx6sxsabresd Revb board, 32M flash is used, but in header file,
CONFIG_SPI_FLASH_BAR is not defined, and we still use SZ_16M.
The LUT initialization qspi_set_lut function uses 32BIT addr,
however CONFIG_SPI_FLASH_BAR and 24BIT addr should be used to
access bigger than 16MB size flash, and BRRD/BRWR should also
be supported. Future patches will fix this.

Add full support for USDHC2, USDHC3, USDHC4 on mx6sx sabresd board.
The default boot socket is USDHC4, so the MMC environment device and
mmcdev variable are set to this device.

Add pinmux settings, implement board_ehci_hcd_init, board_usb_phy_mode
There are two usb port on mx6sxsabresd board:
1. otg port
2. host port
The following are the connection between usb controller and board usb
interface, host port has not ID pin set:
otg1 core <---> board otg port
otg2 core <---> board host port
In order to make host port work, board_usb_phy_mode return USB_INIT_HOST
to make host port work in HOST mode.

Define CONFIG_SYS_FSL_ESDHC_ADDR using USDHC4_BASE_ADDR which is used
in board_mmc_init.
If board_mmc_init failed, cpu_mmc_init->fsl_esdhc_mmc_init will use
CONFIG_SYS_FSL_ESDHC_ADDR to initialize sdhc. So set this macro to
correct value.
