docs: marvell: Update info about WTMI_IMG option 

Default WTMI_IMG value was documented incorrectly. Also WTMI_IMG name may
be misleading as this option does not specify full WTMI image, just a main
loop (e.g. fuse.bin or custom RTOS image) without hardware initialization
code (DDR, CPU and clocks).

For Armada37x0 only, the path of the binary can point to an image which
does nothing, an image which supports EFUSE or a customized CM3 firmware
binary. The default image is wtmi.bin that built from sources in WTP
binary. The default image is ``fuse.bin`` that built from sources in WTP
folder, which is the next option. If the default image is OK, then this
option should be skipped.
Please note that this is not a full WTMI image, just a main loop without
hardware initialization code. Final WTMI image is built from this WTMI_IMG
binary and sys-init code from the WTP directory which sets DDR and CPU
clocks according to DDR_TOPOLOGY and CLOCKSPRESET options.
