[PATCH] arm: renesas: Make R-Car Gen5 u-boot-elf.shdr compatible with SDK flash_writer

[Marek Vasut]

The SDK 4.32 flash_writer tool, built from the SDK IPL source, requires
SREC S7 "Start address (termination)" record [1] at the end of the SREC
file that is sent to it during installation of content into storage,
otherwise the tool waits for the S7 record indefinitelly and the payload
does not get installed into storage.

Specifically, the tool considers SREC S3 and S7 records as mandatory,
S0, S5, S6 as ignored, and any other records as unsupported.

Configure srec_cat such that it explicitly generates the trailing S7
record, and also that it never generates the ignored S5 Count record.
This fixes installation of u-boot-elf.shdr using the flash_writer tool,
which can not finish successfully without the trailing S7 record.
