The QSPI controller in i.MX 6SoloX and Vybrid supports reading data using
IP register and AHB bus.
The original driver only supports reading data from IP interface. The IC
team suggests to use AHB read which is faster then IP read. Using AHB read,
we can directly memcpy, a "missed" access to the buffer will cause the
controller to clear the buffer and use the SEQID stored in bfgencr register
to initiate a read from flash device.
Since AHB bus is 64 bit width, we can not set MCR register using 32bit. In
order to minimize code change, redefine QSPI_MCR_END_CFD_LE to 64bit Little
endian but not 32bit Little endia.
Introduce a new configuration option CONFIG_SYS_FSL_QSPI_AHB. If want to
use AHB read, just define CONFIG_SYS_FSL_QSPI_AHB. If not, just ignore it.
Actually if Vybrid is migrated to use AHB read, this option can be removed and
IP read function can be discared. The reason to introduce this option
is that only i.MX SOC is tested in my side, no Vybrid platform for me.
In spi_setup_slave, the original piece code to set AHB is deleted, since
Vybrid platform does not use this to intiate AHB read. Instead, add
qspi_init_ahb_read function if defined CONFIG_SYS_FSL_QSPI_AHB.

To support bigger than 16MB size qspi flashes, spi framework uses bank
switch to access higher bank or lower bank.
In this patch, QSPI_CMD_BRRD, QSPI_CMD_BRWR, QSPI_CMD_WREAR, QSPI_CMD_RDEAR
is initialized in LUT register with related pad and length configuration.
qspi_op_pp is originally for page programming, this patch reuses this function
for bank register switch and renamed it with qspi_op_write.
Since bank or EAR register is only 1 byte length, however original qspi_op_pp
or now renamed qspi_op_write only support 4 bytes lenght as the access unit,
this will trigger data abort exception when access EAR or bank register.
This is because upper framework passes a 1 bytes pointer to qspi_op_write,
however qspi_op_write treat it as an int pointer. This patch fixes this for
accessing EAR or bank register.
