x86/boot: Fix cmdline_find_option() prototype visibility

Browse source 
ac09c5f43c ("x86/boot: Build the command line parsing code unconditionally")

enabled building the command line parsing code unconditionally but it
forgot to remove the respective ifdeffery around the prototypes in the
misc.h header, leading to

  arch/x86/boot/compressed/acpi.c: In function ‘get_acpi_rsdp’:
  arch/x86/boot/compressed/acpi.c:37:8: warning: implicit declaration of function \
	  ‘cmdline_find_option’ [-Wimplicit-function-declaration]
    ret = cmdline_find_option("acpi_rsdp", val, MAX_ADDR_LEN);
          ^~~~~~~~~~~~~~~~~~~

for configs where neither CONFIG_EARLY_PRINTK nor CONFIG_RANDOMIZE_BASE
was defined.

Drop the ifdeffery in the header too.
