[PATCH v1] LoongArch: Remove CONFIG_ACPI_TABLE_UPGRADE in platform_init()

[Tiezhu Yang <yangtiezhu@xxxxxxxxxxx>]

acpi_table_upgrade() and acpi_boot_table_init() are defined as
empty function under !CONFIG_ACPI_TABLE_UPGRADE and !CONFIG_ACPI
in include/linux/acpi.h, there are no implicit declaration errors
with various configs.

As Huacai suggested, CONFIG_ACPI_TABLE_UPGRADE is ugly and not
necessary here, just remove it. At the same time, just keep
CONFIG_ACPI to prevent build error and give a signal to tell
us the code is ACPI-specific, and also put acpi_table_upgrade()
under CONFIG_ACPI.

  #ifdef CONFIG_ACPI_TABLE_UPGRADE
  void acpi_table_upgrade(void);
  #else
  static inline void acpi_table_upgrade(void) { }
  #endif

  #ifdef	CONFIG_ACPI
  ...
  void acpi_boot_table_init (void);
  ...
  #else	/* !CONFIG_ACPI */
  ...
  static inline void acpi_boot_table_init(void)
  {
  }
  ...
  #endif	/* !CONFIG_ACPI */
