Keymap prefix needs to be set before loading lsp-mode

(setq lsp-keymap-prefix "C-l")

If lsp-keymap-prefix is set after lsp-mode is loaded, it doesn't actually affect the key binding.
From https://emacs-lsp.github.io/lsp-mode/page/installation/:

;; if you want to change prefix for lsp-mode keybindings.
(setq lsp-keymap-prefix "s-l")

(require 'lsp-mode)
(add-hook 'XXX-mode-hook #'lsp)
