spi: zynqmp_gqspi: Fix issue of reading more than 32bits length

As the flash sizes are increasing day by day, QSPI can have devices of
size > 512MB. In qspi driver we are trying to read all the data at once
using DMA.

The DMA descriptor destination size is only 29bits long.

QSPIDMA_DST_SIZE 0xFF0F0804

BITS:  1:0      Reserved to keep word alignment
BITS: 28:2      Number of 4-byte words the DMA will transfer
BITS: 31:29     Reserved: Returns 0 when read, writes ignored

So we can only transfer data of 0x1FFFFFF0(512MB minus 4bytes) bytes.
Anything above will overflow this register and will ignore higher bits
above 29 bits.

Change the DMA functionality if the requested size is greater than or
equal to 512MB to read 256MB chunks.

arm: dts: qcom: Sync pinctrl DT nodes with Linux bindings

Currently for all Qcom SoCs/boards there are separate compatibles for
GPIO and pinctrl. But this is inconsistent with official (upstream) Linux
bindings which requires only a single compatible "qcom,<SoC name>-pinctrl"
and there is no such compatible property as "qcom,tlmm-<SoC name>".

So fix this inconsistency for Qcom SoCs in order to comply with upstream
DT bindings. This is done via removing compatibles from "msm_gpio" driver
and via binding to "msm_gpio" driver from pinctrl driver in case
"gpio-controller" property is specified for pinctrl node.

CONFIG_SYS_TIMER_RATE might be a dynamic value, i.e. a function call
instead of a static value, thus it has to be evaluated at runtime. If it
is a static value, the compiler should be able to optimize the unused
branches out.

This will be needed for kirkwoods dynamic CONFIG_SYS_TCLK setting.
