AOSCOS: MIPS: ls7a_fan: use register addresses in loongson.h

Original driver code expects register definition in loongson-pch.h (where
LS7A register definitions were never merged upstream), which are now
revised and stored in loongson.h.

Miscellaneous register base (LS7A_MISC_REG_BASE) starts at:

  LOONGSON_PCILO0_BASE + 0x80000

According to legacy loongson-pch.h from Lemote. Revise definition for
LS7A_PWM_REG_BASE to be:

  LOONGSON_PCILO0_BASE (LS7A_PCH_REG_BASE in loongson-pch.h)
    + 0x80000 = LS7A_MISC_REG_BASE
  LS7A_MISC_REG_BASE + 0x2000 = LS7A_PWM_REG_BASE
