[U-Boot] [RESEND PATCH v3 0/5] ARM: at91: improve peripheral and system clock handle functions
To reduce the duplicated code, rework the peripheral's and system's clock handle functions, use these functions to replace the clock handle code.
Changes in v3: - fix incorrectly used the indicator '&' to achieve the variable pointer of pmc->pcer and pmc->pcdr.
Changes in v2: - fix checkpatch warning.

Could you please address my question to the last sent version?
---8<--- Isn't the pmc->pcer1 only available on devices which have CPU_HAS_PCR? The old behaviour would be to just access unconditionally the pmc->pcer here. Could you please elaborate?
Yes, you are right.
PCR is introduced from AT91SAM9X5.
I will be careful. Thank you.

Best Regards, Wenyou Yang
Due to introducing the new peripheral clock handle functions, use these functions to clean up the duplicated code.
Meanwhile, remove unneeded header file include, at91_pmc.h.
