crypto: caam - avoid option aliasing with the CONFIG_CAAM_QI build option

In the Makefile, the new build option CONFIG_CAAM_QI is defined conditioned
on the existence of the CONFIG_CRYPTO_DEV_FSL_CAAM_CRYPTO_API_QI, which is
properly defined in the Kconfig file. So, CONFIG_CAAM_QI is just a local
alias for CONFIG_CRYPTO_DEV_FSL_CAAM_CRYPTO_API_QI.

There is little benefit in the source code of having this slightly shorter
alias for this configuration, but it complicates further maintenance, as
searching for the impact of CONFIG_CRYPTO_DEV_FSL_CAAM_CRYPTO_API_QI
requires to grep once, and then identify the option introduced and continue
searching for that. Further, tools, such as cross referencers, and scripts
to check Kconfig definitions and their use simply do not handle this
situation. Given that this is the only incidence of such a config alias in
the whole kernel tree, just prefer to avoid this pattern of aliasing here.

Use CONFIG_CRYPTO_DEV_FSL_CAAM_CRYPTO_API_QI throughout the Freescale
CAAM-Multicore platform driver backend source code.

No functional change.
