This patch series contains several sstc fixes:
(1) Writing to ACLINT mtime should also update the period of S/VS-mode

(2) VSTIP bit of $mip CSR should check both M-mode and H-mode STCE.
(3) Writing to STCE bit may enable/disable sstc extension in S/VS-mode,

The GT-64120 PCI controller requires special handling where:
1. Host bridge (device 0) must use native endianness
2. Other devices follow MByteSwap bit in GT_PCI0_CMD
Previous implementation accidentally swapped all accesses, breaking
host bridge detection (lspci -d 11ab:4620).

We only require the TCG_GUEST_DEFAULT_MO for MTTCG-enabled
frontends, otherwise we use a default value of TCG_MO_ALL.
In order to simplify, require the definition for all targets,
defining it for hexagon, m68k, rx, sh4 and tricore.

The shift amount, tlb_ps, is as much as 64. check "tlb_ps >=64" to fix.

Therefore, we add a timeout parameter to control the duration of the block.

Added "src_hi" and "dest_hi" fields to "AspeedMasks" for 64-bit addresses test.
Updated "aspeed_test_addresses" to validate "HACE_HASH_SRC_HI" and
"HACE_HASH_DIGEST_HI".
Ensured correct masking of 64-bit addresses by checking both lower and upper
32-bit registers.
