core: pager: fix get_linear_map_end()

With paging enabled there is an unpaged portion of OP-TEE which ends at
the address returned by get_linear_map_end(). Without ASLR enabled this
is both a virtual and physical address. However, with ASLR enabled it's
important to keep these addresses apart so add get_linear_map_end_va()
and get_linear_map_end_pa() and use the right function in
phys_to_virt_tee_ram() and is_unpaged().

This fixes occasional errors like:
E/TC:0 0 Panic 'can't find mmu tables' at core/arch/arm/mm/tee_pager.c:549 <tee_pager_early_init>
E/TC:0 0 TEE load address @ 0x50b9000
E/TC:0 0 Call stack:
E/TC:0 0 0x050bf144

with paging and ASLR enabled.

core: pager: fix tzsram_end in init_runtime()

With pager enabled tzsram_end in init_runtime() is supposed to be a
virtual address. However TZSRAM_BASE is a physical address so this only
works as long as virtual and physical addresses can be used
interchangeably. With ASLR enabled this is not the case so fix this to
compensate for the offset between physical and virtual addresses.

drivers: stm32_rng: remove millisecond timeout with interrupts masked

Removes the 10ms timeout monitored waiting loop in stm32_rng_read_raw()
that was called with interrupts masked. stm32_rng_read_raw() is
renamed read_available() and does not pool a hardware status: it
either returns or reads samples according to RNG state.

Changes stm32_rng_read() to monitor RNG burst generation with a 100ms
timeout. This timeout threshold targets that at least few REE ticks
(dozen of ms) allow RNG to conceal and synchronize upon bad conditions.

As change rewrites function stm32_rng_read(), it also removes a zeroing
of the buffer on sample generation error. The wiping is removed since
pointless.

imx_ocotp: correct ocotp fuse address computation

Not all the imx platforms have the same bank spacing. In particular
the imx6 and imx7ulp both have bank sizes that are twice as large
as the imx8m.

The ocotp_get_die_id_mx7ulp() function was written with the
old computation, so bank 2, work 6 would be 0x4e0 offset.
Using the new calc, bank 1, word 6 would be 0x4e0 offset.

So all the bank values should move to bank 1.

This will set the correct computation.
