init: Do not build logo.c when initlogo is disabled

PS2: Fix spacing.

"For now, logo.c was build even if TARGET_NO_INITLOGO was true.
Changing tty to KD_GRAPHICS is now done in init.c as it should be, when
the logo is not present."
This fixes weird framebuffer distortion on certain devices, if
TARGET_NO_INITLOGO is set to true in some device makefile.

init: Allow load of lpm.rc by parsing a cmdline argument

A usage example could be:
BOARD_LPM_BOOT_ARGUMENT_NAME := lpm_boot
BOARD_LPM_BOOT_ARGUMENT_VALUE := 1
Where lpm_boot is the argument to read, and 1 the value of it when kernel says we should enter offline charging mode
