  hw/arm/boot: Set PC correctly when loading AArch64 ELF files

The code in do_cpu_reset() correctly handled AArch64 CPUs
when running Linux kernels, but was missing code in the
branch of the if() that deals with loading ELF files.
Correctly jump to the ELF entry point on reset rather than
leaving the reset PC at zero.

  hw/arm/virt: formatting: memory map

Add some spacing and zeros to make it easier to read and
modify the map. This patch has no functional changes. The
review looks ugly, but it's actually pretty easy to confirm
all the addresses are as they should be - thanks to the new
formatting ;-)

  sd: sdhci: Fix ADMA dma_memory_read access

This dma_memory_read was giving too big a size when begin was non-zero.
This could cause segfaults in some circumstances. Fix.

  target-arm: A64: fix TLB flush instructions

According to the ARM ARM we weren't correctly flushing the TLB entries
where bits 63:56 didn't match bit 55 of the virtual address. This
exposed a problem when we switched QEMU's internal TARGET_PAGE_BITS to
12 for aarch64.
