clk: remove unused __clk_[get|put] ...

This is some unused code resulting from copying stuff from the
kernel. Remove it.

clk: Add is_enabled callback ...

This allows us to better detect whether a clk is enabled or not.

- If we can ask a clk, ask it. If it's enabled, go on and ask parents
- If we can't ask it, but it can be enabled, depend on the enable_count.
  if it's positive, go on and ask parents
- If we can't ask it and it cannot be enabled, assume it is enabled
  and ask parents.

This makes the CLK_ALWAYS_ENABLED unnecessary, since the fixed clk now
always returns 1 in its is_enabled callback.

mtd: Add parameter to allow erasing bad blocks ...

While erasing bad blocks is a potentially dangerous operation
it is sometimes needed during development or when some foreign
code has touched the flash.

This patch adds a device parameter 'erasebad' to allow erasing
bad blocks. Since this is not wanted during production this is
behind a Kconfig option.

mtd: nand: do not write empty pages ...

Do not write pages which only contain 0xff. UBI expects pages which
seem empty to be writable. This got lost with:

| commit 3139c3e
| Author: Sascha Hauer <s.hauer@pengutronix.de>
| Date:   Thu Nov 29 11:16:40 2012 +0100
|
|    mtd core: call driver write function with complete buffer
|
|    mtd->write is supposed to loop around pages internally, no need
|    to do this in mtd_write. This fixes a huge write performance drop
|    with the m25p80 driver when it was converted to a mtd driver recently.
|    Since mtd->writesize is 1 for this driver mtd_write ended up doing
|    single byte writes on the flash.

Introduce mtd_all_ff as a global function since UBI currently has its own
implementation.
