In the current implementation, in case of I2C arbitration lost, a retry is
attempted; the message counter and pointer are reset to the original values
and the I2C xfer process is restart from the beginning.
However the message counter and message pointer are respectively
decremented and incremented by one before attempting any transfer, causing
the 1st transfer not to be actually retried (in case of a single transfer,
nothing is actually retried at all).
This patch fixes this: in case of retry, the 1st transfer is also retried.
Tested on a ZynqMP Kria board, with upstream older u-boot, but the involved
file and underlying logic seem basically the same.

Failure can happen when i2c is used without initializing pinctrl properly,
which U-Boot happily allows in SPL. Without this fix, further I2C access would
fail, even after proper pinctrl initialization.

K3 GP devices allows booting the secure binaries on them by bypassing
the x509 header on them.
ATF and OPTEE firewalling required the rproc_load to be called before
authentication. This change caused the failure for GP devices that
strips off the headers. The boot vector had been set before the headers
were stripped off causing the runtime stripping to fail and stripping
becoming in-effective.
Separate out the secure binary check on GP/HS devices so that the
boot_vector could be stripped before calling rproc_load. This allows
keeping the authentication later when the cluster is on along with
allowing the stripping of the binaries in case of gp devices.

In non-combined boot flow for K3, all the firewalls are locked by default
until sysfw comes up. Rom configures some of the firewall for its usage
along with the SRAM for R5 but the PSRAM region is still locked.
The K3 MCU Scratchpad for j721e was set to a PSRAM region triggering the
firewall exception before sysfw came up. The exception started happening
after adding multi dtb support that accesses the scratchpad for reading
EEPROM contents.
The commit changes R5 MCU scratchpad for j721e to an SRAM region.
