Solve the problem that TX16S is stuck and unable to start

Reduce the number of retries of SD_MAX_VOLT_TRIAL to solve the problem that the card owner cannot enter the system during the boot process of TX16S.

Hello,
I bought my new TX16S mark2 two months ago. Since the beginning my radio sometimes turns off without warning even though the battery is fully charged and there are no bad contact. This hapened 6 times. I have to turn on the radio to use it. Have you ever heard of this problem? Do I have to update the software? It runs on Edge tx 2.6.0
Sorry foer my poor english I'm french ;-)

Sorry to hear that @tipiouk. This isn't quite the right place to discuss this, so I've started a discussion at #3666 to continue with this.

Merging this into main so it gets stress tested. The review commentary indicates that it was reduced from 65536 retries to 2100 based on many, many cycles of repeat testing and trying to establish a minimum number that reduces the likelihood that the user thinks the radio is locked up, and is sufficient to ensure other issues such as the splash screen not working don't occur.
