Add support for building U-Boot for Cortex-M33 RSIP core in Renesas R-Car Gen5 R8A78000 X5H SoC. The main goal is to start U-Boot on the Cortex-M33 RSIP core, which initializes the hardware and then starts the Cortex-M33 SCP and Cortex-A720 cores which run the SCP firmware and applications software respectively. The SCP is responsible for platform resource management, and is used to start other CPU cores. The Cortex-M33 build contains its own r8a78000_ironhide_cm33_defconfig which configures the build for aarch32 instruction set compatible with the ARMv8M core. The build also uses -cm33 DT and -u-boot.dtsi which are derived from their non-CM33 counterparts, and add CM33 specifics. The arch/arm/mach-renesas/u-boot-rsip.lds is derived from generic arch/arm/cpu/u-boot.lds with adjustments to cater to the RSIP core, those are entrypoint before vectors, __data_start/__data_end symbols for data-only relocation, and placement of BSS into read-write SRAM area.

The 64-bit R-Car board code is currently unbuildable on 32-bit ARM cores. Skip DRAM initialization bits to make the code compatible with these cores, because those cores do not use the DRAM, they only use SRAM. Signed-off-by: Marek Vasut <marek.vasut+renesas@mailbox.org>
Replace s_init() early initialization at the end of lowlevel_init by invoking the same code in mach_cpu_init(). The mach_cpu_init() is called a bit later, but as the code initializes timer and no code uses timer until mach_cpu_init(), this does not pose a problem.

Remove DECLARE_GLOBAL_DATA_PTR from files where gd is not used, and drop the unnecessary inclusion of asm/global_data.h. Headers should be included directly by the files that need them, rather than indirectly via global_data.h.

Add initial support for Renesas R-Car X5H R8A78000 Ironhide board. This consists mainly of DTs, Makefile and Kconfig entries and board specific configuration files. The DTs will be gradually switched over to Linux DTs via OF_UPSTREAM once Linux DTs become available upstream, as upstreaming progresses.

This function is currently a misnomer at times as we have cases where it
passes arguments to the image. In preparation for making that be a more
common case rename this function to jump_to_image(...). In order to do
this, rename jump_to_image in board_init_r(...) to jumper so that we do
not have a conflict.
