[PATCH v2 4/5] ARM: i.MX8M: cosmetic cleanup

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

From: Marco Felsch <m.felsch@pengutronix.de>

Rename the local imx8m_atf_start_bl31() to imx8m_tfa_start_bl31() since
the official naming is Trusted-Firmware A (TF-A) and not ARM Trusted
Firmware which was the former name.

While on it rename the parameters to make it clear what firmware
component is passed and align the function documentation with the
reality.
