arm: omap3: Enable clocks for peripherals only if they are used
This patch change the per_clocks_enable() function used in OMAP3
code to enable peripherals clocks. Only required clock should be
activated. So if the board use the uart(x) as a console we need
to activate it. The Board's config should include define to enable
every subsystem that the board use. For a complete list
of affected peripherals, registers CM_FCLKEN_PER and CM_ICLKEN_PER
should be checked.
Right now the bootloader can enable and disable clocks for:
uart(x) using CONFIG_SYS_NS16550
gpio bank (x) using CONFIG_OMAP3_GPIO_X with X = { 2, 3, 4, 5, 6 }
i2c bus using CONFIG_DRIVER_OMAP34XX_I2C.
Not required gptimer(x) and mcbsp(x) for booting are disabled by default and
are not supported by any define.
Their activation need to included in the per_clocks_enable if the
peripheral is included. Not booting board should enable the peripheral
clock connected to their driver

If no softreset save registers are found on the hardware
"bootcount" is stored in the environment. To prevent a
saveenv on all reboots, the environment variable
"upgrade_available" is introduced. If "upgrade_available" is
0, "bootcount" is always 0 therefore no need to save the
environment on u-boot boot, if "upgrade_available" is 1 "bootcount"
is incremented in the environment and environment gets written
on u-boot start.
So the Userspace Applikation must set the "upgrade_available"

if a boot was successfully.
