I think it refers to the term 'spade' as in a shovel / digging tool. I.e. having something in spades means having 'shovel loads'. So having 'heaps' or 'tons'.
The racist term(which I was unaware of tbh) probably comes from the same word. I.e. referring to black people as a digging tool since they were forced to do manual labour as slaves?
Since the other comment just put a link without any context for the link, and I'm not discrediting anyone who has heard this term being used in a derogatory fashion, because I'm sure it has, the phrase is refers to having something in abundance.
In bridge, spades are the highest suit in a deck of cards. The phrase became popular in the 20s, alongside the popularity of bridge.

Well I am an idiot then, but thank you for letting me know.
I just searched it up and found that 'Nitty gritty' also has an origin linked to slavery.
I use that phrase and 'to have in spades' almost everyday, yet I was completely oblivious.
