Subject: [PATCH v3 0/2] mark spi clocks as critical and enable spi3 clocks

Hi,

This patchset enables spi3 clocks by marking critical clocks as
CLK_IS_CRITICAL and in the meantime replaces the use of
CLK_IGNORE_UNUSED for spi1 clocks.

The sclk needs to be considered critical as well.

The SPI3 in the tm2/tm2e boards will control an irled for remote
controlling.

Changelog:

V1 -> V2
 - the "sclk_spi3" doesn't need to be enabled in boot time as it
  is handled by the spi driver itself.

 - use the CLK_IS_CRITICAL flag for the ioclk

V2 -> V3
 - some more tests has confirmed taht "sclk_spi1,3" need to be
   enabled as critical!

 - added Chanwoo's review in the second commit.

Thanks,
Andi
