arm-trusted-firmware-stm32: rework patch for the RTC configuration

Browse source 
A patch was added upstream to temporary enable RTC clock configuration only
for STM32MP15 boards. Use this patch instead of reverting commit 03a581e2.
Now for STM32MP135 boards RTC clock configuration is handled by optee-os.

Subject: [PATCH] fix(stm32mp1-fdts): re-enable RTC clock
This reverts commit 703a581e2522bffe21b421c98994dc02aed2934c.
On STM32MP15 ST boards, RTC clock configuration by OPTEE is not ready
yet. Re-enable it temporary to get LSE as clock source of RTC.
