mako: reduce the power consumption in off-mode charging

In off-mode charging, we don't need to turn on CPU1 to CPU3.
So we turn off CPU1 to CPU3 in off-mode charging. By doing this
we can save 60mA.

charger: Do not suspend when disconnecting from charger

The device should be power off when disconnecting from charger.
If the device enter to suspend, the device couldn't handle the power off
process. So the device shouldn't suspend to handle the power off at that time

make_ext4fs: fix dentry padding when dentry size is 4088 or 4092

When the total dentry size is N * 4096 - 4 or N * 4096 - 8, there is
not enough room in the block to insert an extra padding dentry.
Instead, switch to always padding the previous dentry out to the end
of the block, which matches what the kernel does when creating new
directory entries.

Also fix dentry_size to return the size of all the dentries
without the padding, the len + 8 padding is incorrect, and the
DIV_ROUND_UP will round up to the correct number of blocks.

Nexus 4に関するアップデートが多いので、近々ビルド番号JOP40GがNexus 4に降ってくるかもしれません。

また、カスタムROMの中にはすでにAndroid 4.2.1_r1.2(JOP40G)対応のものもリリースされています。
