[PATCH] ACPI / amba: Drop unnecessary check for registered amba_dummy_clk

[Youwan Wang <youwan@nfschina.com>]

amba_register_dummy_clk() is called only once from acpi_amba_init()
and acpi_amba_init() itself is called once during the initialisation.
amba_dummy_clk can't be initialised before this in any other code
path and hence the check for already registered amba_dummy_clk is
not necessary. Drop the same.
