crypto: stm32: fix stm32_cryp CTR mode on small input buffers

Fix missing cast when saving pre-computed masks in STM32 CRYP driver
CTR implementation when several small input data is provided to
the update handler.

The issue could be found, for example, by assigning STM32 CRYP to OP-TEE
in stm32mp1-157C_DK2 board DTS file (patch below) and running xtest
regression_4017 with level 15 ("xtest -l 15 regression_4017").

Example of a patch on stm32mp157c-dk2.dts file to use CRYP driver for
AES operations:
+&cryp1 { status = "okay"; };
+
&etzpc {
st,decprot =
(...)
- <DECPROT(STM32MP1_ETZPC_CRYP1_ID, DECPROT_NS_RW, DECPROT_UNLOCK)>,
+ <DECPROT(STM32MP1_ETZPC_CRYP1_ID, DECPROT_S_RW, DECPROT_UNLOCK)>,
(...)
}

tree-wide: use power-of-2 rounding macros where applicable

Use ROUNDUP2(), ROUNDUP2_OVERFLOW(), ROUNDUP2_DIV() and ROUNDDOWN2() at
