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

Add support for -R (recurse) to init chown builtin.

This is helpful for setting ownerships on entire directory trees,
such as sysfs and selinuxfs, particularly when the precise set of
files is dynamically generated at runtime.

init: uevent: Add msm video symbolic link handling

Create meaningful symbolic links for video encode/decode
devices based on link_name sysfs node so that video client
doesn't have to rely on dynamic dev node names like device32,
device33 etc.

init: Check for symlinks with lstat() not open()

Using open() with an O_NOFOLLOW flag will result in a file falsely
being determined to be a symlink if the open fails for another
reason.

For example, a character device that isn't ready due to the
underlying hardware not being initialized yet will fail to open()

An example of this are any CG2900 device files prior to
execution of ste-cg29xx_ctrl

This uses lstat() instead of open() with O_NOFOLLOW to check
whether a file is a symlink or not.
