staging: android: Add some Kconfig help entries
This commit adds Kconfig entries for the following:
1: ANDROID_BINDER_IPC
2: ASHMEM (additional text)
3: ANDROID_LOGGER
It also changes "Register" to "Registers" in
ANDROID_LOW_MEMORY_KILLER
Finally, all "help" instances are changed to "---help---",
as recommended by kconfig-language.txt in order to visually
aid developers.

config ANDROID_BINDER_IPC
bool "Android Binder IPC Driver"
default n
+ ---help---
+ Binder is used in Android for both communication between processes,
+ and remote method invocation.
+
+ This means one Android process can call a method/routine in another
+ Android process, using Binder to identify, invoke and pass arguments
+ between said processes.
config ASHMEM
bool "Enable the Anonymous Shared Memory Subsystem"
default n
depends on SHMEM || TINY_SHMEM
- help
+ ---help---
The ashmem subsystem is a new shared memory allocator, similar to
POSIX SHM but with different behavior and sporting a simpler
file-based API.
+ It is, in theory, a good memory allocator for low-memory devices,
+ because it can discard shared memory units when under memory pressure.

config ANDROID_LOGGER
tristate "Android log driver"
default n
+ ---help---
+ This adds support for system-wide logging using four log buffers.
+
+ These are:
+
+ 1: main
+ 2: events
+ 3: radio
+ 4: system
+
+ Log reading and writing is performed via normal Linux reads and
+ optimized writes. This optimization avoids logging having too
+ much overhead in the system.
