Subject: [PATCH] gdbserver: include linux-arm-tdesc.h in linux-arm-tdesc.c

When building with -Wmissing-declarations, I get:

  CXX    linux-arm-tdesc.o
/binutils-gdb/gdb/gdbserver/linux-arm-tdesc.c:29:1: error: no previous declaration for 'const target_desc* arm_linux_read_description(arm_fp_type)' [-Werror=missing-declarations]
   29 | arm_linux_read_description (arm_fp_type fp_type)
      | ^~~~~~~~~~~~~~~~~~~~~~~~~~
/binutils-gdb/gdb/gdbserver/linux-arm-tdesc.c:49:1: error: no previous declaration for 'arm_fp_type arm_linux_get_tdesc_fp_type(const target_desc*)' [-Werror=missing-declarations]
   49 | arm_linux_get_tdesc_fp_type (const target_desc *tdesc)
      | ^~~~~~~~~~~~~~~~~~~~~~~~~~~

Include linux-arm-tdesc.h in linux-arm-tdesc.c to fix it.  And because
linux-arm-tdesc.h uses the arm_fp_type, it should include arch/arm.h as
well.

gdb/gdbserver/ChangeLog:

	* linux-arm-tdesc.c: Include linux-arm-tdesc.h.
	* linux-arm-tdesc.h: Include arch/arm.h.
